Fetus interrupts mid-Sex, anyone else?

So i know this is going to sound weird and TMI (hence the section) but my husband and i were having sex for the first time in a little over 3 months. I’ve had a pretty low sex drive since I’ve gotten pregnant (currently 19 weeks), but I just came back from a week long business trip and when we were cuddling in bed we started getting heated. We had to keep switching positions and tempo because some were less comfortable than others due to my bump and overall pleasure (I’ve suffered from a mild case of vaginismus that flares every so often). Then in the middle of missionary I’m guessing the baby starts to get too uncomfortable to where she just starts to give me such severe increased pressure to my uterus that i had to stop and come out of the position and sex all together. I could swear... she popped her little head out to the right side of my lower abdomen. I’m still on my back and the pressure is still there and all i feel and and clearly see is a huge bump on the side of my right lower abdomen peeking out (like that scene where the alien is popping out of the stomach). My husband was so intrigued and he just started to poke and press on it all while i had to say, “stop it that’s just more pressure~” He rarely gets to feel her kick because as soon as he puts his hand on her she’ll stop, but even though she wasn’t kicking she was veeery obviously there.

I was pretty bummed that we had to stop what we were doing and couldn’t continue because the baby was in distress but we didn’t push it since we felt bad. Has this ever happened to any of you that can already feel the baby?
