A hematoma, also spelled haematoma, is a localized bleeding outside of blood vessels, due to either disease or trauma including injury or surgery and may involve blood continuing to seep from broken capillaries. A hematoma is benign and is initially in liquid form spread among the tissues including in sacs between tissues where it may coagulate and solidify before blood is reabsorbed into blood vessels. An ecchymosis is a hematoma of the skin larger than 10mm.They may occur among/within many areas ...

Approximately 20% of pregnant women have some form of bleeding in the first trimester of pregnancy. Often this is not a cause for concern, but examination by a doctor is mandatory to establish the specific cause and take timely and adequate measures if necessary.

If bleeding occurs in the second and third trimesters, immediately seek medical help without any delay.

Menstruation-during-pregnancy---myth-or-reality

Menstruation during pregnancy - myth or reality

Menstruation-during-pregnancy---myth-or-reality_0_0

In the not-too-distant past, women have not had access to so much information, and cases of so-called "black lives" have not been accessed. "colored pregnancy", in which the woman realizes that she is months pregnant after conception, were not such ararity.

Menstruation-during-pregnancy---myth-or-reality_0_1

The bleeding that occurs in a colourful pregnancy is not a real menstruation - although it may occur around the time it is expected. This may mislead the woman that she is not pregnant until the fourthmonth.

Menstruation-during-pregnancy---myth-or-reality_0_2

The phenomenon is due to the dropping of parts of the mucous membrane of the uterus (endometrium), which is not yet covered by the growing fruit bag of the embiroxon. After the 16th gestational week, the fruit sac has completely taken over the surface of the mucous membrane, and the bleeding stops.

It can be established that the woman is pregnant if she doubts that something is wrong and visits her gynecologist. The condition is not dangerous.

Hormonal changes as a cause of bleeding at the beginning of pregnancy

Hormonal-changes-as-a-cause-of-bleeding-at-the-beginning-of-pregnancy_1_0

Another reason for such bleeding is hormonal changes. In this case, some women have a slight bleeding about 4 to 8 weeks of pregnancy or around the time their menstruation should occur. This can be very confusing and is why these women do not realize that they are pregnantfor a while.

Hormonal-changes-as-a-cause-of-bleeding-at-the-beginning-of-pregnancy_1_1

In this case, usually bleeding stops around week 13, since at this point the placenta is developed enough to produce all the hormones needed to maintain pregnancy. In particular, progesterone, whose deficiency makes the lining of the uterus unstable.

Embryo implantation can also cause mild bleeding or spotting

Embryo-implantation-can-also-cause-mild-bleeding-or-spotting_2_0

Another possible explanation for the bleeding, which can fool us that it is the onset of menstruation in a very earlypregnancy, is implantation bleeding , which looks more like spotting and can occur around the moment of the first late menstruation.

Embryo-implantation-can-also-cause-mild-bleeding-or-spotting_2_1

However, implantation bleeding occurs only once - in the first month of pregnancy. It is due to the destruction of small blood vessels in the process of implantation or "nesting" of the fertilized egg in the uterine mucosa. It lasts only a day or two, it is quite light and has a pink or brown color. [<a href="/p/6_prvonachalni_simptoma_na_briemiennostta_4cecc476_1151_4208_8c02_40531579bf2b" target="_blank" rel="noreferrer">ref. 3</a>]

Besides implantation bleeding, after the egg is implanted in the endometrium, sometimes this leads to slight bleeding, which on early examination turns out to be a small hematoma (blood collection). This is not something to worry about. The hematoma will gradually disappear, and in most cases the pregnancy is preserved without complications.

Polyp-or-erosion-of-the-cervix

Polyp or erosion of the cervix

Polyp-or-erosion-of-the-cervix_3_0

In some women, polyps of the cervix are formed - the area that connects the uterus to the vagina. Under the influence of increased hormonal levels during pregnancy, the polyp can grow. Its surface is easily wound and can bleed during sexual contact or even only with physical exertion on the part of the mother. Polyps are not usually treated during pregnancy.

Polyp-or-erosion-of-the-cervix_3_1

Erosion of the cervix (also known as cervical ectropion) can be a cause of spotting or bleeding. Blood supply to the uterus and its cervix increases during pregnancy, and the cervix can bleed painlessly without causing problems. Erosion can also cause bleeding after intercourse, and this type of bleeding should also always be reported to the obstetrician-gynecologist.

Infections

Infections_4_0

Besides harmless causes of bleeding, which do not require treatment, but only observation, there are several worryingreasons , for which bleeding can also be observed in the firsttrimester.

Infections_4_1

Infections_4_2

Such a cause are infections with certain microorganisms, such as chlamydia, trichomones, herpes, gonorrhea. They should be treated , as they can cause miscarriage and other complications of pregnancy. Treatment is mandatory under the supervision andon the prescription of the attending obstetrician-gynecologist.

Molar-pregnancy

Molar pregnancy

Molar-pregnancy_5_0

Molar pregnancy is a type of gestational trophoblast neoplasm. This is a very rare disease in which severely elevated levels of the pregnancy hormone HMG, abnormally rapid growth of the abdomen, bleeding, severe vomiting are observed.

Molar-pregnancy_5_1

In molar pregnancy, abnormal tissue develops instead of a baby. In rarecases, this tissue can be cancerous and metastasize. [<a href="https://www.bioseek.eu/bg/eng/research/pubmed/Current_management_of_molar_pregnancy_12063873" target="_blank" rel="noopener">ref. 5</a>]

Molar-pregnancy_5_2

It is believed that sometimes it is likely that molar pregnancy is due to an egg without or an egg with an inactivated nucleus fertilized by spermatozoa, which has doubled its own chromosomes.

Molar-pregnancy_5_3

Molar pregnancy does not end with baby wear.

Ectopic-pregnancy

Ectopic pregnancy

Ectopic-pregnancy_6_0

In ectopic pregnancy, the fertilized embryo is implanted outside the uterus, usually in the fallopian tube.

Ectopic-pregnancy_6_1

If the embryo continues to grow, this can lead to a violation of the integrity of the fallopian tube, which can be life-threatening for the mother. Although ectopic pregnancy is potentially dangerous, it is observed only in about 2% of pregnant women.

Ectopic-pregnancy_6_3

Other symptoms of ectopic pregnancy are severe cramps or some pain in the lower abdomen around the ovaries and dizziness. Bleeding is more of a brownish spotting.

Ectopic-pregnancy_6_4

In ectopic pregnancy, the home pregnancy test may be positive, but with a negative and doubt, a blood test and examination are carried out. Ectopic pregnancy is dangerous for the mother and therefore its interruption is necessary.

Miscarriage-or-"missed-abortion"

Miscarriage or "missed abortion"

Miscarriage-or-"missed-abortion"_7_0

Since miscarriage is most common in the first 12 weeks of pregnancy (until the 20th c.), it is one of the most serious causes of bleeding in the first trimester. However, bleeding during this period does not necessarily mean that we have lost the baby or will have anabortion.

Miscarriage-or-"missed-abortion"_7_1

Other symptoms of miscarriage are severe cramps in the lower abdomen and tissues leaking through the vagina.

Miscarriage-or-"missed-abortion"_7_2

The cause of miscarriage is not always known, but in some cases this occurs due to improper development of the embryo or a problem with the pregnancy itself. In 50% of miscarriages, the cause is chromosomal abnormalities in the fetus.

Miscarriage-or-"missed-abortion"_7_3

Of course, for most women, miscarriage is a very sad and disturbing experience and they need the strong support of partners and loved ones. Usually in her grief the woman blames herself, but in the vast majority of cases she is not at all at fault!

Miscarriage-or-"missed-abortion"_7_4

Miscarriage-or-"missed-abortion"_7_5

Symptoms of miscarriage are different. In some cases, there may be only a slight spotting, in others the bleeding may stop and more severe bleeding with clots and pains may occur again. Sometimes there may be no bleedingat all.

Miscarriage-or-"missed-abortion"_7_6

The so-called "mysed abortion" or interruption of the embryo's cardiac activity in the early stagesof pregnancy , often established during a routine examination at thegynecologist. [<a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/missed-abortion" target="_blank" rel="noopener">ref. 7</a>]

Miscarriage-or-"missed-abortion"_7_7

In these cases, termination of pregnancy is necessary, since it has no chance of development . In case of early pregnancy loss, part of the tissue may remain in the uterus. This tissue must be removed. This can happen by allowing the tissue to pass naturally, or it can be removed with the help of medicationor surgery.

Miscarriage-or-"missed-abortion"_7_8

Whatever the cause of bleeding during any stage of pregnancy, consultation with a doctor and seeking medical attention are mandatory , in order to preserve the life and health of the mother and, if possible, the fetus. Bleeding should not be taken dramatically, especially before the causeis established. Let us think positively, but take the necessary measures to make the situation happy. :)
