sex question 🙈

So this is probably a stupid question but I am a ftm so idk 🙈 I haven't been told by my doctor or anything to not have sex so my hubby and I go at it when we get the chance. Lastnight he put me in a super awesome position (missionary with legs up around his head) which felt awesome but then we got into it and he kind pushed my legs so they were bent up against my stomach kind like a frog and went to town 😂🙈 It was awesome but afterwards because I felt kind squished during, I was afraid it might hurt the baby (16.5wks). I didn't mention it to him and I feel great today, no weird symptoms so I figure no but just want to be sure 🙈
