I had a period August 12th that lasted until the 16th. I had sex maybe on the 20th, and 24th. I started another period September 1st (15 days later) which was very, very heavy to the point that I checked myself into the hospital this cycle ended on the 6th. They said that it could have been a early MC or just an irregular cycle, they did two ultrasounds and did not see anything. Yesterday I started cramping again September 14th (7 days after the bleeding ended) to the point where I'm going to the bathroom to check if my cycle has started and it hasn't. Why am I cramping again? What is going on? And has this happened to anyone before? Thank you all.
