Late & Exhausted

I am now 17-18 days late, so exhausted I can’t keep my eyes open, and experiencing spotting. I keep feeling like my period is starting, but it doesn’t. The spotting is brown. I have a tingling in my breasts and some pain occasionally.

With my son, I tested positive at 4 weeks, I’m still getting negatives with potential lines? I also had terrible breast pain with my son, this isn’t consistent.

My doctor won’t test until I have a positive hpt. I’m so lost, any advice would be appreciated. I’m attaching my last test for reference.
