I started Nuvaring on Monday the 17th of August on the first day of my period which came 2 days early. I continued it for the next few weeks and spotted moderately the whole time. I had unprotected sex with my boyfriend on Wed the 2nd of Sept which would have been day 16 on the ring. He also withdrew. I removed the ring on that Friday the 4th, the 18th day on ring to have my period a little early cause it was like I was having it anyways and on Sunday Morning the 6th I passed a piece of tissue with bad cramping that had what look to be a small sack. Theres a small chance I could have been pregnant from having sex the beginning of July b4 starting bc so could this have been an early miscarriage?. I had taken plan B and got a light period right on time after so didnt think i was pregnant. We also had sex that Sunday the 6th and he withdrew. I inserted a new ring on Sat. the 11th, 7 days after removing it and had sex the 12th, the 2nd day of new ring, and he withdrew. I worried that by removing the ring early might have allowed me to get pregnant. Are my chances high if I had been on the ring and he always withdrew even with me taking it out early and also if that had been a miscarriage, bleeding stopped 2 days after, what are the chances of me getting pregnant 10 days after? Thanks so much!
