condom stayed inside me 😳

So the other day me and my boyfriend were having sex eugh a condom. Anyway he pulled out before we'd finished because we wanted to change position and the condom had stayed inside of me. It was hanging out so I managed to get it out. Is it possible I could get pregnant? I'm not on any form of bc because of health reasons and he didn't come. But later that day I had stringy white discharge and now I've got lower abdominal pains. My periods not sure for another 15 days. I know I'm probably worrying for nothing
