HELP (sex problem )

Me and my boyfriend recently had sex June 25th. We first did where he was on top and when we changed ways, I had like white stuff on me. I asked a friend and they said it was my own stuff.  But the condoms were still intact? He checked after we did it. Also he decided to flip it over and spill EVERYTHING on my carpet. 😂 but really though should I take a test for just in case?
