question: Hello doctor, I and my partner had intercourse two days ago. He used a condom but can I still have a chance with pregnancy. But two days after intercourse my stomach starts to hurt and I am spotting blood. I have read about spotting to be a sign of pregnancy but after a week after intercourse can it just be my period? My period had to start in nine days, but my periods are irregular. Can they come up to more than a week early or late? Please suggest I do not know what is going on.
