I've been on BC for about 2 months now and I'm pretty good about taking my BC everyday at the same time but yesterday and the day before that I forgot! I've been on my period for about 2 weeks now and I've had unprotected sex. I'm still bleeding and it's gotten really heavy. I also usually don't get cramps when I'm on my period but lately I've had mild ones. I'm concerned that I might be pregnant but I was on my period when I had sex, so I'm not sure. Can anyone help me understand what's going on?
