I had sex 2 weeks ago which was right around the time I should star ovulating. The next day my breasts were tender and my right ovary has been aching since. The tenderness is normal for me durring that time of the month but I am now 2 days late and have sharp little cramps. I've been tired the past couple of days, have had a couple of dizzy spells and my breasts are still really tender. Could I be pregnant even if I am having slight sharp cramping?
