I had two periods this month. I am sexually active and trying to have a baby. The first one was my normal regular menstrual cycle on the 5th of April, then another one on the 21st of April. The second one was spotting for 3 days, then heavy for 2 1/2 days, then spotting again for 2 days. Not sure what to think this has never happened to me before I have normal periods each month. What should I do? What is this?
