Sex while pregnant

My husband and I haven’t had sex in about 2 months now. I’m pregnant and it is just really uncomfortable, we do other stuff but we’ve never went this long in our entire relationship. We decided to stop trying after I had bleeding and lost part of my mucus plug the last time, I was shaken up and it felt like it caused more issues than it had benefits. My ob says my cervix is fine and there’s no reason not to try. We’re going away for our anniversary in a few weeks and I really want to atleast try and have sex with my husband. Any tips would really be appreciated. It just feels like really “tight” and it’s so different than not pregnant sex. Has anyone else dealt with this? How did you cope? Was there any thing that made it feel more comfortable for you?
