Sore labia after sex in pregnancy

I’m 24 weeks and had our normal sex with lube. I’m feeling lots of pressure in my labia/vagina area. It just feels really tired and heavy and sore. It’s kinda crazy because it was just a quickie! I did prenatal yoga after and it hurt to do the warrior poses.

I had noticed that my labia and clitoris looked bigger than normal (not while having sex, I noticed in the shower a few hours b4 having sex). So I’m guessing that the pregnancy is increasing pressure down there and that’s leading to swelling.

Anyway, anyone else gone thru this after or noticed swollen vagina? Tips for how to deal and manage sex in the future?
