Okay my back hurts and my stomach keeps hurting periodically. I also keep feeling pressure. Just went for a short walk and it didn't help much. The cramps aren't that strong just feel like mild period cramps and will last a minute or so, but my back hasn't really stopped hurting. My mil says start timing but I don't wanna get my hopes up. What do y'all think?
