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.
