Anal & Pregnant.. Tips?

Ja

So I’m 16 weeks pregnant and I’ve never had anal with my boyfriend. I’ve had anal with one night stands and definitely wasn’t sober so i don’t remember how it went.. My bf really wants to have anal and I just want some advice. Did you have anal pregnant? Condoms or Raw? Im worried about the 💩 aspect of it all being pregnant im either super constipated or loose stool. On the bright side, I have lube!
