Welcome to HCM,
As your last menstrual period was on 25th Feb, the expected date of ovulation was 9th March, presuming your menstrual cycle of 28 days duration. Fertilization of egg can take one day more. Thus, suppose fertilization took place on 10th March. If you calculate from 10th March, age of Fetus on 15th April will be 5 weeks & 2 days. At this fetal age placenta is in the primitive stage. What was the colour of the bleeding/discharge. Pinkish or brown spotting
can be placental bleeding, which usually subsides within 2-3 days, but fresh bleeding is not a good sign. Please consult your Gynaecologist.
Wish you good health,
