Did he cum?

Hey guys so my boyfriend and I did it yesterday and we started oof with a condom but half way through it was pinching him and since I’m on birth control (depo 3 shots so far) I said it would be okay if he took it off well he was doing his thing and he got the feeling he was about to cum but then he got a pinch in his back and it was gone well he pulled out a bit later and when I stood up it was like really wet down there when I went to go check the liquid had no smell to it and was clear he had given me oral before we started so I’m wondering if that was the cause but he doesn’t think he came but I don’t know help?
