Pregnancy sex

Ka

Hey guys, I need tips on having sex while pregnant. We haven't had much of an issue since I wasn't really showing too much until now and it makes it hard to have sex I am currently 28 weeks. I was advised to avoid positions that require me to be on my back, me on top always gives me cramps on my belly for some reason, and doggy style (what we have been doing) is starting to feel kinda impersonal lol. Any tips are helpful! 😊
