37 weeks and SO much pressure?!

Tatjana
Looking for some opinions and maybe personal experience..
I'm 37 weeks pregnant with my second baby, and I have been having so much pressure and shooting pains way down below (vagina & even my behind 😳) if I'm walking I have to constantly stop because I get this shooting pain (lightning crotch) but not just in my lady area, it's also been happening in my behind. Ahhhh. I've had this every now and then for the last like 2 weeks but today it's been all day where I'm dreading getting up to walk. I had to go to the grocery store and probably looked like a total weirdo because I kept stopping mid-walk and just stood there lol.
Had anyone had this happen close to labor? I never felt this with my first, and the pressure I didn't feel until I was in labor. Maybe this baby is just big and low? Just curious who else had this and when, and when you went into labor.
I can't imagine feeling this another possible 3 weeks, especially since I have a 1 year old to chase around its getting near impossible . 🙏💕👶🏼
