His cum or mine?

Okay so this is quite confusing and I’m not sure whether I should be worrying or not. I’m seeing this guy and I went to his house today, things escalated and we had sex. Bare in mind I haven’t had sex for at least 5 months. He was quite shy and I couldn’t tell if he cummed or not but it seemed like it when he pulled out I felt something wet. It didn’t look like his come but it was a lot of clear fluid on his bed and me. Would this be his cum or mine? I’m starting to panic as I’m on the pill but we didn’t use a condom
