A pink discharge after ovulation may be a first sign of pregnancy as it normally happens after the fertilized egg implantation, which is the moment when the embryo adheres to the uterine walls and starts to develop.
Right after implantation, the fertilized egg starts producing a hormone called beta hCG, which can be detected in the bloodstream. Therefore, women who have a pink discharge after ovulation and would like to know whether they're pregnant, should do a beta hCG blood test 1 day after a missed period.
The following table indicates the beta hCG levels in the blood in the first weeks of pregnancy:
Beta HCG levels in the blood test
Not pregnant - Negative - or test carried out too early
Less than 5 mlU/ml
3 weeks of pregnancy
5 to 50 mlU/ml
4 weeks of pregnancy
5 to 426 mlU/ml
5 weeks of pregnancy
18 to 7.340 mlU/ml
6 weeks of pregnancy
1.080 to 56.500 mlU/ml
7 to 8 weeks of pregnancy
7.650 to 229.000 mlU/ml
How to identify implantation discharge
Implantation discharge can be similar to egg white, either watery or milky, but with a pinkish color. This kind of discharge can happen one or two times after implantation. Some women present a similar texture to mucous or catarrh, with some strings of blood, which can be seen on the toilet paper after urinating.
Nevertheless, not all women can observe this type of discharge, and, therefore it shouldn’t be considered a definitive pregnancy symptom.
