AM I OK????!!! PLS HELP

Hello! So I'm on the pill (have been for 2 months) and I also use condoms cause I always want to be super protected (don't want any pregnancies!!)

I had sex with my boyfriend and when we finished I had some type of whitish discharge down there. We checked and the condom did not break and it didn't slip off or anything.

But since I'm always worrying I took the plan b pill like 2 hours after.

Has this happened to anyone else? Like I don't know if the white stuff was semen or just discharge. Is it possible that it was cum if the condom wasn't broken?

And of it was I'm protected right? What are the chances I could we pregnant??

Thank you in advance!!!
