It could also be a yeast infection which is very common in pregnancy due to hormonal changes.. monitor your vaginal discharge and get a swab test
This happened to me too, it happened the first time, then a few weeks later we tried again and it was completely fine, but recently tried again and I had the burning. I really don’t know either but it’s put me off again. I might try a lube next time
Happened to me last week. It’s put me off to be honest. I get my urine checked weekly and it’s not a uti for me. I’ve read up that pregnancy can cause sex to be painful sometimes, so I’m just putting it down to that. Edit: I’m 23 weeks 1 day now xx
