Crying after sex?!?!

So I’m 16 weeks pregnant, still pretty early. My fiancé and I were just watching comedy movies when one thing lead to another and we had sex. It felt great don’t get me wrong, but he doesn’t like me being on top because he gets claustrophobic really easily, but then he doesn’t last very long in many other positions so that’s our dilemma. After he finishes he wiggles which is my cue to get down, and I asked for a kiss first, he kinda got upset that I know how he gets but I didn’t get down automatically. So I got down and I could feel it building up in my eyes but I didn’t want him to see. So I crawled to the end of the bed got a bottle of water and just silently cried as he fell asleep. Kinda just want some emotional help right now, I’m a wreck most of the time but I never cry after sex.
