Im not sure if I am pregnant or not but Im concerend that I am. My period was on time but not as regular as always. I have always had regular periods. Periods last 5 days and first 3 days are the heaviest. This time my period was only heavy first day with more cramping then usual. The other four days there was very light bleeding. But this time I am on day 7 of my menstral with spotting like bleeding. Could I be pregnany?
