When to see a doctor?

Hey Ladies,

I'm hoping for advise from others who have experienced this or know of someone who has and can let me know the road to travel.

Today (6-18-18) marks 6 days late for my period.

I've taken 4 tests (about every other day) and they have all read negative.

I don't have symptoms of a impeding period and I didn't have them leading to the projected date.

Symptoms I DO have:

Hunger, even if I eat enough I'm still hungry sooner than usual.

Headache, it's pretty much constant.

Lower back pain. its constant.

Fatigue.

and a weird pressure like feeling in my lower abdomen.

I'm 31. My periods are seldom ever late and I can't remember a time I skipped for more than 3 days.

Admittedly, I have a terrible OB, she seems bothered if I go in for anything so I am curious if there is a designated time I should set an appointment that will be acceptable at this point.

We are TTC, so the lack of Flo and the negative tests are frustrating.

Any help is appreciated ♡
