Last month I missed my 20th active pill, quickly took it the next day and took my last active pill of the month later that day. Exactly a week later, on my last placebo pill, I had sex with my boyfriend without a condom but he pulled out. I just found out that I was not fully protected on my birth control and I'm starting to freak out about being pregnant. I get my period in a week and I am extremely paranoid. Do I have a likely chance of being pregnant?
