Is it normal to have diarrhea everything month around the time i ovulate? this happens every month, ever since i stop my birth control

Likely normal: There are many manifestations of hormonal effects of menstruation and ovulation. Some experience constipation, others experience diarrhea. While other hormones probably contribute, prostaglandins may be a culprit in some of the diarrhea you are experiencing. If you want to try something to slow the diarrhea down I suggest adding fiber to your diet even in the form of capsules. Stay well.
