12 weeks issue TMI

So it’s 4am and I was woken at 1 am by a burning discomfort in my vagina. Like it was swollen and just hot.

Back round info: My husband and I haven’t had sex for a few because I have been having hip pain but yesterday night we decided to have sex.

So back to this am, I have now been up and uncomfortable needing to pee but also constantly NEEDing to poop. But constipated!

I’m 12 weeks and don’t know if this irritation is just vaginal irritation from having sex for the first time in a while?

Or if this is the start of uti? (No pain with peeing just hot down there)

And if this constipation has anything to do wit it 🤷🏽‍♀️ any help would be great!
