So my boyfriend and I had sex three times from September to mid October, and I got a normal period on October 20 (heavy the first 2-3 days, then normal last 3 days). We haven't had sex after my last period at all and it's December 2, and I still haven't had my period since October 25. As always, me and my boyfriend are extremely careful when it comes to sex. He urinates before we have sex, he uses a condom throughout the activity, he does it slowly to prevent the condom from tearing and that he pulls out 30 seconds before ejaculating WITH a condom. We also fill the condom with water every time and make sure there were no tears or holes, and there weren't any the last 3 times we did it. I was certain I wasn't pregnant until I realised I never had my period on November. I've heard of stories of females still getting their period throughout their pregnancy, and some even finding out they were pregnant 3-4 months later because of their recurring menstruation with almost no symptoms. I'm freaking out and don't know what to believe, so please help me out and let me know what you think!
