Hi, I had unprotected sex with my girlfriend on 29th July and she took a i-pill on the same day later. She had her periods on 22nd July. After a week of taking the pill she had some bleeding like in periods on 5th and 6th August. Unfortunately we had unprotected sex on 17th August again. I wanted to know if 17th August can be considered in safe period and she can avoid take i-pill this time as we are aware of the possible side effects of i-pill, it messes with the hormones and period dates. Please help, it's been 24 hrs since we had sex and we have very little time to decide on it.
