Hello Doctor, I am 33 year old. Usually I get my periods in 32 or 33 days. This time I got it on the 39th day. However, unlike other times, this time I am bleeding less, and slight cramps and loose motions with dark colored stools.. 6-7 times a day. I had constipation for 3 days before the periods started. What could be the reason for the lose motions? Should I see a Doctor?
