Weird cramping, late, but possibly no positive test (may just be evap since it took a long time to show)?Anyone had a similar situation?

So here's the thing- I am now two days late. I'm NEVER late. I've taken several tests (all negative except this one) and I'm pretty sure this is an evap line (it wasn't positive before 5 minutes), but I want it to be an actual positive so bad. About 4 or 5 days ago, I had what I think is some kind of cramping so bad I almost left work. I've never had cramps before so its definitely odd. I was sore until yesterday from my day or two of cramping. Tylenol wouldnt touch it. My husband and I recently moved and I haven't found a new OB here. I called and none I want are taking new patients without a positive test.

Has anyone had a similar situation? I was really hoping the cramping was implantation but it seemed too intense to be that. And I can't get in with an OB since I'm not sure I'm pregnant 😭😭
