Implantation bleeding: how to recognize it

You want a baby, jerk and worry whether it worked out this time with the pregnancy - and then the shock: You find some blood in your panties. Menstrual Period or Implantation Bleeding? Pregnant or not? Here is how you can tell the difference and what happens during implantation bleeding.

Nesting - what exactly is it?

After ovulation and fertilization the egg cell migrates with the help of fine cilia through the fallopian tube towards the uterus. It reaches the uterine cavity after six to eight days. It has now matured into a blastocyst, the size of a pinhead and with a fluid-filled cavity in the middle. In the uterus she finds a thick, soft layer of mucous membrane. As soon as the blastocyst has found its place, a hollow forms in the wall of the uterus, into which the germ sinks. This is how the blastocyst connects to the mother's body. A thin skin then forms over the hollow so that the germ is completely covered. The penetration of the egg into the upper layer of the uterine wall is also called implantation. The cells on the outer layer are now developing into placentathat the unborn baby will soon take care of. From now on the germ is called an embryo. You can read what exactly and very clearly here happens from ovulation to implantation in the woman's body.

And this can lead to bleeding?

Sometimes yes. During implantation, maternal and child tissues grow together. This includes the fact that existing blood vessels dissolve and new ones arise - and this can naturally lead to light bleeding, usually unnoticed inside the body. If the woman discovers some of the blood in her panties, such bleeding is often referred to as implantation bleeding. Gynecologists also speak of nidation bleeding or implantation bleeding.

Then there are the controversial implantation bleeding as real?

To Dr. Alexander Braun, Head of the Winterhude Gynecological Practice Clinic in Hamburg: “The keyword“ implantation bleeding ”does not appear in the specialist literature because light bleeding in this phase of early pregnancy is a natural process that actually does not play a role for mother and child. Strictly speaking, this is an embarrassment diagnosis to give a name to a perfectly normal process. In my practice, however, I often simply say that this is a slight bleeding in early pregnancy that is not a cause for concern. "

Why is implantation bleeding so often discussed in fertility forums?

For women who want to have children who have been waiting for a baby for a long time and possibly already Fertility therapies have lived through, there is often a great deal of uncertainty. When they are finally pregnant, they are usually very afraid that the dream of having a baby could be over very quickly. Therefore, of course, even a slight bleeding is a cause for concern. Since light and harmless bleeding is not uncommon in early pregnancy, the term “implantation bleeding” has become established to explain such harmless bleeding.

Can there be any other reason for easy bleeding?

Yes. Under the influence of Hormones in early pregnancy the tissue inside the cervix loosens. It is delicate and can bleed very easily if touched, such as during sex. Plus, bright red bleeding in early pregnancy can also be the first symptom of a Miscarriage be. But in this case the bleeding would tend to get heavier.

Is implantation bleeding a good or a bad sign of pregnancy?

Dr. Braun: "Neither of the two. In my experience, such visible light bleeding occurs in around a quarter of women in early pregnancy. But it is not a bad sign if you do not notice the implantation."

What does the blood look like if there is an implantation bleeding?

It can look light but also brownish. Light-colored blood can be seen when the bleeding is acute. Brown blood means that it has been some time since the bleeding and the blood has collected in the uterus before it drains.

When does implantation bleeding occur at the earliest, when does the latest occur?

The earliest point in time for implantation bleeding is one week after fertilization, the latest two to three weeks after fertilization, i.e. possibly at a time when the woman is not yet aware of the pregnancy and a pregnancy test is not yet positive Result shows.

Some women report having their periods even though the urine test showed they were pregnant. Can this be?

Period and pregnancy are actually mutually exclusive, because there are two opposing hormonal processes behind them: During the cycleFrom ovulation onwards, the lining of the uterus continues to build up to create a nest for the fertilized egg cell. If the egg is actually fertilized, the mucous membrane becomes stronger every day under the influence of the pregnancy hormones. If the egg cell is not fertilized, the body receives a hormonal signal that the thick layer of mucous membrane is not needed in this cycle. So it is expelled from the uterus, which can be seen as a menstrual bleeding.
However, in early pregnancy, in addition to harmless bleeding, slight pulling abdominal pain can also occur. They occur when the uterus begins to stretch slightly and are a classic symptom of pregnancy. If a woman feels this dragging while she is bleeding lightly, around the day of the missed period, it is very understandable to confuse these symptoms with the period. Especially if the woman had only slight pain and bleeding during her period.
In rare cases it actually happens to women Light bleeding for several months during pregnancy always at the time when they would otherwise have had their period. This bleeding also comes from the lining of the uterus, but has nothing to do with pregnancy.
