I'm 5 months postpartum, my cervix is really low, soft and open about a cm, i also have an increase in discharge. no period yet. could i be pregnant?

Prolapse: How do you know your cervix is low? can you see it? can you feel it at the opening of your vagina? How long did you push? How big was the baby? It sounds as if you have prolapse of your uterus. Have you had unprotected intercourse? Seek evaluation from a gynecologist and perhaps they can give you exercises to do, or fit you for a pessary.
