My menses ended on 17th June then I had unprotected sex on 29th June then took the first postinor 2 pill the morning after we had sex then we had unprotected sex again before I took the second pill. We had sex again the following day then I took the first postinor 2 pill and then the second postinor two pill 10 hours later. It's been a week now and I haven't seen any bleeding just really thin watery discharges. Could I be pregnant?
