When Implantation Bleeding Occurs

Implantation bleeding

Irema Fertility Clinic – In the first weeks of pregnancy, when the woman is still unaware of her pregnancy, it is very possible that she confuses implantation bleeding with menstruation. Therefore, in today’s post we are going to go deeper into this concept.

What is implantation bleeding?

Implantation bleeding usually occurs in the second part of the menstrual cycle, when the inside of the uterus is preparing to receive a possible pregnancy.

When does implantation bleeding occur?

Fertilisation of the egg takes place in the fallopian tubes, the egg heads towards the uterus, before it divides into more cells. When it arrives, it approaches one of the internal walls and nests in these, which may cause a small haematoma that is expelled outwards, thus giving rise to implantation bleeding.

When implantation bleeding occurs, the inner walls of the uterus are heavily irrigated and have a large number of blood vessels, which are necessary for the growth of the embryo.

What is implantation bleeding and how can it be identified and differentiated from menstruation?

Around 30% of pregnant women experience implantation bleeding. It is very important to be aware of its existence in order to avoid unnecessary concerns, especially in women who are undergoing assisted reproduction treatment.

Some of the main differences between implantation bleeding and menstruation are as follows:

Implantation bleeding colour and texture

Its colour, as menstrual bleeding is usually a deeper shade of red and implantation bleeding is usually dark red or even brown.

The texture of implantation bleeding is usually lighter than that of menstrual bleeding, and implantation bleeding is usually thin and clot-free.

How long implantation bleeding lasts

Implantation bleeding does not usually last more than a few hours or a couple of days at most, while menstruation usually lasts from 2 to 7 days. The menstrual flow is changeable whereas implantation bleeding occurs only once.

Does implantation bleeding hurt?

Implantation bleeding should not be painful, there may be slight discomfort in the abdomen or similar to menstruation itself, but never intense and sustained pain. Last but not least, implantation bleeding in itself is not a risk of miscarriage.

What should I do if implantation bleeding occurs?

If you are not entirely sure what to do in this situation, we recommend that you go to your gynaecologist for reassurance. He or she will help you and will come to the right conclusion.
