Question.

I don’t like looking up answers on google. I’d rather ask here where there are women.. because i’d rather ask people who are experienced than for the internet to tell me something wrong. I’m young . 20 . I had sex last night with my boyfriend. And we were drunk and really into it, and he came inside of me. We usually have protected sex. I have a Kyleena IUD, in which i did my research on ..And it is super effective, 99% effective it says in preventing... but i got it when i wasn’t sexually active because i needed birth control to help regulate my period.. and my period for this month is about to start. Can i still get pregnant? I feel like it’s a stupid question but you never know. I’m worried.
