My boyfriend and I had unprotected sex four days into my ovulation period (I realized after). He pulled out and it got all over my leg. So I thought I was probably fine. I'm on my 30th day cycle (<a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> says I should start my period tomorrow) but I don't think I'm going to start anytime soon. Do you think my chances of pregnancy are high?
