###Human: There was no withdrawal bleeding after I-pill and I miss my period now. Can I be pregnant? ###Assistant: Hi. I have seen many ladies taking I-pill post unprotected sex are unable to get withdrawal bleed. But they can have heavy bleeding in the same menses during which they had sex, or they can have prolonged bleeding during the periods when the I-pill was taken in the proper dose, timings and without vomiting. You can also do a blood pregnancy test if you feel anxious. The result would be less likely positive as the sex was not under a fertile period. You can have a menstrual induction. Take tablet Primolut 10 mg (Norethisterone) twice daily for five days and wait for bleeding for one to weeks.
