37+2 need advice

So I have been getting Braxton Hicks on and off for weeks, not painful no big deal. Today I am having a stabbing pain above my pelvic bone in low abdomen, it comes on quick and painful and then subsides, almost feel crampy I guess. I went to church and felt like baby was pressing on my cervix a few times. At my last appointment I was 1 centimeter dilated and 50% thinned, that was on Friday but my doctor seems to feel I have a couple more weeks to go since I didn’t seem to be progressing rapidly. So what could these pains mean?
