I’m freaking out

Abs

Me and my boyfriend had sex and he came in me 5 times. I’m very worried that I could get pregnant. I talked to 2 doctors and they said it’s very rare. I’m just worried because I have the worst luck in life. Oh and by the way I been on nexplanon since September. It’s also been a few hours and I’m in such bad pain it feels like a period but this is not the time I have them. Being on nexplanon I haven’t had my period my all except for once.
