It's totally normal. I looked at mine in the mirror and wanted to cry - I'm 37 weeks. It's just from all the extra hormones and increased blood flow. It does eventually go back to normal but it's scary when your body changes so much hey!
It's normal, mine is swollen too! It freaked me out when I saw it, I'm 37 weeks. I don't remember this from my previous pregnancies.
At some point in ur pregnancy ur vj will get swollen. Its totally normal nothing to be worried abt.good luck
