So I had sex on my birthday (8/5) and my boyfriend finished inside me without my consent and I was mad at him at first but then I was like oh well he's gonna buy me plan b, so he did. It's been over 3 weeks I haven't started my period, my boobs are bigger and really tender, and I feel sleepy all the time. I honestly feel like I am pregnant. My last period was July 16, 2016. What do you girls think?
