I had my period about three weeks ago and it was not normal, it was very light and lasted only a few days. I have been having weird pains in my stomach all week, sharp peirecing pains. But I took a HPT and it was negative. My cycle is normally 28 days, exactly. And I should be ovulating as of yesterday, and I have tested myself for ovulation for the last few days, and I am not ovulating. COuld I be pregnant and in an early stage. Can you still ovulate if you are already pregnant? Any help is apprecited...
