33 weeks pregnant lightning crotch

I’m 33 weeks pregnant and the past couple days I think I’ve been getting lightning crotch.

That’s the best way to describe the feeling also.

I’ve also had back pain and mucus like discharge.

Think baby girl is just laying super low? Should I get a belly band?

I don’t think it’s anything to go into dr for just need suggestions on how to help as I have a 2 year old I’m chasing!
