I took a plan b 3 days after

So this past Tuesday i had sex with my current bf and he came inside me after i said not to, and he was supposed to get it but he was lying to me so i had to wait until friday when i got paid to get it. I got it, took it and now im just waiting. Im still kind of freaking out cause of how long i had to wait. I really don't want to be pregnant right now cause of my life situation and i dont want to raise my child like this. I just think its fucked up because i told him many Many times not to do that. AND WE EVEN GOT CONDOMS Idk how it fuckin came off and im sure he just took it off without me knowing. I just hope im okay. #blessmyuterus
