Had sex for the first time

Earlier today I had sex for the first time with a friend that I have known for around a month or so. We used a condom but it broke so he took it off and we kept going and pulled out and jerked and came on my thigh. But I am worried that a piece of the condom could be still inside me, is there a way to check and know if it is out because I can’t go to a doctor since I’m a minor and don’t want to tell my parents lol
