I’ve been getting lingering cramping feeling in my pelvic area this past few days, I get a lot of pressure as well, there mild but it do make me want to go poop. This is my 4th baby I don’t remember having this with my other kids. Is labor near? I have a doctors appointment I rather hold off till then to get check out. I do drink plenty enough of water I know I’m not dehydrated.
