hi i am 25 years old male, i had unsafe sex with my lover , 3 weeks ago ,who is 19 years old. I am not sure while sex whether i ejected or not. Now its been a week that she had not ovulated.Are there any pills which can prevent pregnancy even after 3 weeks ?. but Before this also we had un-safe sex , she took emergency contraceptive pills, by which she did not get pregnant, she had her period much earlier than the usual.
Can she take abortion pill now,if she can please tell the proper dosage (time and after how many hours or at what time in a day). but it is not confirmed that she is pregnant?
