So on June 7th (Saturday) my boyfriend and I had sex with a condom for like 20 seconds. We're not sure if he came inside of me or not but I'm still worried. I took plan b two hours after we had sex. Then the next day (Sunday) I started birth control pills. My period is still in a week but is there a possibility that I could be pregnant from that? I've been taking my birth controls consistently ever since June 8th onward.
