Kay so, I usually get my period around the 15, & I didn't get it until today, april 25. Me and my boyfriend had unprotected sex the 13 and he pulled out but said some still got in. So we then had unprotected sex again, the 21 and he didn't pull out. I was spotting yesterday, april 23, which was 10 days after the 1st time we had unprotected sex. And now I'm having heavy bleeding and small cramps. Am I pregnant?
