When a female has her period than a week aft er it s over have intercorse and start bleedin agin?

Family practice : Being arroused causes increased blood flow to the vaginal wall. Sometimes you may have some spotting. But irregular menstral bleeding is abnormal. Possible hormonal imbalance. See your dr if it persists.

Transitional phase: I'm going to assume that you are talking about yourself at age 52. These are probably the end of your periods. This means there is already going to be some irregularity, regarding frequency, duration, and intensity of periods. I believe you had a normal period, had sex, and then had a menopausal abnormal bleed. There is the possibility of thinning, irritated vaginal mucosa being torn from sex, too.
