I was on the pill (combined) for 7 months. I was supposed to start a new pack on the 27th of October since my period was due that day. I missed that pill and later on that same night my boyfriend and I had unprotected sex. He ejaculated outside, then put it back in for a few strokes. Got my period a couple of hours later. What are my chances of getting pregnant if now I’ve missed 4 pills and currently am on my period. If so, when should I test? I have a 24 day cycle.
