What should I do? URGENT

Me and my boyfriend had sex tonight and he had a condom on. He was sitting on a chair and I rode him until he came. We have done it before in the past with no issues but today as I got off him. It looked like the semen fell down and out of the condom onto his balls. Well what we think is semen it was white but when we wiped it, it was pink and I had white discharge this morning. So I’m not sure what it could be and if I should be worried about it ???
