Possibly...: This could represent problems on the cervix or uterine abnormalities like polyps or fibroids. More often than not it is not anything to worry about. We would check your vagina- cervix for abnormalities if someone is concerned and it is a persistent happening. Otherwise, we would ask you to track this and if continues, would bring you into the office for evaluation.

Yes: Do a pregnancy test and if negative also check for cervical infections.
