Should I be worried about spotting 7dpo? I'm normally 28-30 day menstrual cycle. Had unprotected 6 days before I ovulated. We didn't even finish....

Can take a test. It is possible you are pregnant. In another week or so, try taking a home pregnancy test. Ovulation can be difficult to predict solely on the timing of menstruation since it can vary a bit from month to month. In addition, a pregnancy can occur even if the man does not ejaculate inside the vagina. If you are trying to avoid pregnancy, be sure to discuss contraceptive options with your doctor.
