I have irregular periods that used to be regular. In January 2018 I had a pelvic ultrasound done and a regular ultrasound done. They saw no fibroids, no cysts, nothing. They said I don’t have PCOS or endometriosis. They told me everything looked perfect. Is it possible to develop something in 2 years? We’re TTC and the irregular periods are making that hard. My OB said that it is very unlikely and that since I had that done already that she isn’t worried. I have really heavy periods that are extremely painful. Have any of you experienced this?
