Hello,
After unprotected sex, if you took emergency
contraceptive pills within 72 hours of unprotected sex, you need not worry. Emergency contraceptive pills are very effective if taken in time. It can cause
hormonal imbalance so you can have scanty period, heavy period, your periods may go irregular.
Black blood is a sign of old blood that is coming out. It is indicative of blood that takes a longer time to leave the uterus and has become oxidized. No worries. You should watch for early signs of
pregnancy. If you do not have any early sign of pregnancy, then don't take stress. Avoid
anxiety, stress and take adequate rest, Take home-made food rich in iron, calcium and protein. You can take
iron supplements.
Take care. Hope I have answered your question. Let me know if I can assist you further.
