I'm almost 39 wks now but since like 30 wks I had it all the time my Dr. Told me it was the way the baby was laying I also had a lot of pressure in my pelvic area hope it gets better hun cuz I've been absolutely miserable as of now I can nearly walk but I go Monday for my csection! :) so I can't wait!! Good luck and congrats
How long have you had those symptoms for? I'm 33 weeks and will get symptoms like that every few days, they always go away eventually tho. I think sometimes baby just gets into an uncomfortable position. If they persist or continually get worse tho, it could be signs of labor and you should call your doc.
