I should have kept better track of this but didn't. I stopped using nuva ring the end of October. I took it out early because it causes me a lot of discomfort. I immediately got my period and it lasted about 2 weeks, so it ended early November (I don't remember exactly when). Since then I have yet to have my period, it was suppose to show two weeks ago, based off of what my regular cycle was, but never did. I have had unprotected sex many times since taking the ring out and I am now experiencing cramping, hot flashes, dizziness, and severe nipple pain (TMI, I know!). Are these just side effects of coming off birth control or could I be pregnant?
