I been having sex with my botfriend for about 5 months now and my last period was nov 16.2010 but before than I always get it on the 21 of each month now it's December 16 2010 and I have yet to get my period.. on top of that about three weeks ago I have been extra tried and my left brest is very sore and leaking a white liqude and I been feeling cramps in my tummy and a little back pain.. I do feel like I have to throw up but I never do and I have been a tab moody so can you help me please and tell me what's wrong could I be pregnant or am I going through a change... thank you for taking time to answer my ?

Pregnancy is possible, but it could just be that you're having an off month. Pregnancy symptoms and PMS symptoms are very similar.

The only way to diagnose pregnancy is by taking a pregnancy test. It may still be too early. If you usually get your period on the 21 I'd at least wait until then to test. After is better. Use first morning urine when you test, it's more accurate.

Thanks a lot I will do that... this was a great help I'm less worried
