I started using Nuvaring on the 19th of September. I had unprotected sex with my boyfriend on the 21, 22 and 23. He didn't pull out and we didn't use a condom and when I checked my dates I was fertile from the 17-23 and ovulated on the 22nd. So technically I started using nuvarig while I was fertile, had unprotected sex the day before I ovulated, the day of ovulation and the day after ovulation. What does this mean? I doubt I'm pregnant because I've had unprotected sex before and never got pregnant...
