Women’s Tips – Can chemical pregnancy evolve?

Gianna Coelho – The dosage of HCG in the blood tends to double every 48 hours in a normal pregnancy. If this value does not change or decrease within this period, we may be facing a chemical pregnancy. In these cases, the important thing is to exclude other diagnoses, such as having a positive pregnancy test and not having anything in the uterus when performing the ultrasound exam. In addition, it is essential to exclude the possibility of ectopic pregnancy, which can occur in the tubes, ovaries and even the pelvis. But once a positive test is detected, this pregnancy can evolve if there is no other factor that prevents this development.

How long after chemical pregnancy does menstruation begin?

If this embryo fails to implant properly, menstruation may follow soon afterward, often a week late. There are women who do not even make the diagnosis of this pregnancy.

Can chemical pregnancy prevent future pregnancy?

The fact of having suffered a chemical pregnancy does not compromise the woman’s reproductive future, just as attempts at a new pregnancy can already be started in the next cycle.

Can chemical pregnancy occur in in vitro fertilization?

In patients undergoing in vitro fertilization (IVF), fertilization of the egg by the sperm has already taken place in the laboratory, and the implantation of the embryo in the patient’s uterus depends on the body’s natural mechanisms. In many women, the HCG measurement is performed on a pre-established day with a positive result, but the pregnancy does not develop.
