Hi.. I'm a little embarrassed to ask this but what are the chance of me getting pregnant if my partner and I had unprotected sex and he came inside of me and then 36 hours later I took plan b. After I took the plan b about an hour later we had unprotected sex again and he came inside me. I'm not sure if we repeated the action again but if so it would've been within the same hour as the second time. I'm also on Tri Lo Sprintec but I skipped my first pill on accident so I took it with my second pill. I also waited a about week to have unprotected sex like the birth control package says to when you accidentally skip a pill. I think the unprotected sex happened with the second week of my pill pack. I'm supposed to start my period tomorrow.
