Me and my girlfriend had unprotected sex on 17 Jan, on the same Day she had taken i-pill within 5 hrs, then she had her periods on 27 to 31. On 1st Feb, we had another sex at morning, then she took i-pill for that. At the same day we had sex again at 2 o'clock and she took another i-pill. Now she is having pain in stomach and vaginal bleeding, what should we do? When can we go for home pregnancy test? Should we have to go to a gynecologist for this?
