Hi,
Thanks for posting in HCM.
I understand your concern.
It would be advisable to take 'emergency
contraceptive pill' or 'morning after pill' when you have
unprotected intercourse. They contain 'levonorgestrel'.
It needs to be taken within 72 hours of having unprotected intercourse. Earlier it is taken, the protection seems to be better.
It would protect from pregnancy by causing
breakthrough bleeding just like periods within 3 weeks from the day of intake of pills. In case you do not get periods within 3 weeks, you need to seek medical attention immediately.
Since these pills are hormonal preparations, common side effects of such pills include nausea or vomiting, dizziness, tiredness, headache, breast tenderness,
bleeding between periods or heavier menstrual bleeding and lower
abdominal pain or cramps. However, most of these symptoms subside with the onset of bleeding.
Hope the information provided would be helpful.
Best Wishes.
