So I had unprotected sex on wednesday and it was the last day of my period. I started my birth control for the first time on monday of that same week and got my period last thursday so when i started it i was within 5 days of starting period. I’m on the combination birth control. We were in the water and it was just like 7 strokes and he didn’t finish inside of me. My cycles are long so I’m pretty sure i dont ovulate right after my period. Am i good?
