Patient: I had unprotected sex 5 days ago, (my boyfriend pulled out) since that day I had mild cramps in my lower abdomen until yesterday, when I had the worst cramps I have ever felt in my lower abdomen, I still feel a little funny today like cramps could occur, I have been moody but that’s the only other sign, I’m supposed to get my period in 6 days, but is this a sign of pregnancy?

Doctor:
