Late but negative tests

So I’m 1-2 weeks late.

Have a bunch of “pregnancy” symptoms but negative tests.

Today I started having lower left back pain.

Has anyone else been through this? I’m soooo close to going to urgent care. My OB can’t see me until July and I’m miserable.

Out of breath, tired, nausea, my favorite things now make me sick, lower left back pain, every now and then minor cramps, I’m SUPER gassy and probably more but I can’t think.

HELP
