I always get very sore breasts 4-5 days before my period is due but this week I did not; which is strange to me. My boyfriend and I aren't trying to get pregnant but we aren't really preventing it. My period is due tomorrow and I feel nothing like I do before my period starts. Help!! Could I be pregnant?

Yes, you could be pregnant. If you don't get your period tomorrow, wait 2 weeks and take a HPT using your very first morning urine. Or go to the doctor to get a blood test. But either way you still need to be 2 weeks late.
