10 days ago my fiancé and I had sex ofcoarse we used protection but I'm not on the pill. 2 days later I caught a stomach virus from my sister. I did not use anti-biotics. But now I'm scared because my period is late. My periods are usually predictable. Ive never missed one since I've began menstrating. Could I be pregnant or could the virus be delaying my period. I haven't tried anything cause I don't know what to do
