Weird pains

Tanisha
This is my second baby and I don't remember ever having this many discomforts with him. I never got BH till a week before I delivered and I've now had them since about 20-22 weeks. But in the last week or so I've had serious throbbing pressure on what feels like my cervix and throbbing not pain from my lower back up to about the middle then it come all the way to the front, that all happens at one and lasts about 1-2 minutes and that lasts for about an hour or so but come about every 10 minutes or so. But I also have a grinding feeling on my pelvic bone when I sit. I go and see the dr tomorrow to ask him about all of this, I'm just wondering if anyone else is experiencing anything like this.... I'm 30w3d now
