My boyfriend and I had sex 5 days before my period was due. He pulled out. Now, I am 10 days late. My period is not regular sometimes I bleed every 28 days, or 29, the longest i have had is 35 days. But now it's already the 40th day. Could I be pregnant? I have no period pains or any other symptoms of period at all. I am taking Vit c for 3 days already to induce my period. Last night I had blood spotting but still no period. Could I be pregnant?
