I came off of the Nuvaring just over a month ago and had a really heavy period. I've had sex 4 times with condoms since stopping the Nuvaring and my period is 3 days late. The last time I had sex was a week before my period was due. I had been on Nuvaring for just over a year. Could I be pregnant? I don't know if the stress is making me late or if my hormones are out of whack since I'm no longer on birth control. I'm really nervous.
