Good evening, My question focuses more on what is the possibility of me being pregnant. At the beginning of this week, Friday morning around 4 in the morning I just started using the Nuvaring, first time using birth control. Well my doctor explained to me that I could just put it in my vagina and I was in the clear. I would be good to go. so I, naively, was under the impression that it took immediate effect. So that same night my partner and I has sex without using condoms or the pull out method, so he ejaculated in me three times. Then once more last night but the sperm didn t stay in, to put it crudely. My main question is what is the percentage, I guess you could say, about me being pregnant? I am 20 years old, an athlete, and I ve never been pregnant before.

### output:

Hallow Dear, NuvaRing is an effective hormonal contraception. It is effective after you insert it on the day of menstruation. If you have inserted it as late as on or after day 5 of the menstruation, then the ring requires 7 days to start its effect and hence some additional protection like condom is advised in such situation. It all depends on which day of menses you inserted the ring. The very fact that you had many sessions of intercourses on the day of ring insertion means that your menstrual bleeding had stopped. So it must be beyond day 5 of the menses. Then you were not protected against the pregnancy on that day. If it is so, you have the following options to assess your pregnancy status: 1. Opt for Beta Chat Doctor test on the blood 10 days after the last intercourse. Values under 5 mid/ml denote no pregnancy while values more than 25 mid/ml are diagnostic of pregnancy. 2. Alternatively you may wait for your menses after removing the ring after 3 weeks. If within a weeks time you do not get menses, the chances of pregnancy are quite high. Then 15 days after removal of ring, you may perform pregnancy test on overnight morning first urine sample. I hope this helps you today.
