30 days late

Kaitlyn
My last period was 7/22/16. I have been regular for the past yr at a 32day cycle to the day. Now im 30 days late completely passing up my last period, 2 days due for my next period. In the past when ivr been late its never been over 2weeks and ill feel "signs" then test and start the next day once i see the bpn. Well ive tested once every week since 1 week post period due date in August. Ive been so so hungry this past month. My nipples havr been hurting and stomach cramping occasionally in the lower abdomen area. I keep saying its all in my head because its never worked out for me and I always start my period. Ive never been told i have any medical condition to say i couldn't have children it just hasnt happened. IF i was to be pregnant, the day of conception the last thing on my mind that weekend would have been to get pregnant. Now my nerves are going crazy because idk whats going on. I want to know either way but i can get into a dr until OCT 3. Anyone else experience this late of a missed period, 3 negatives and still something come of it? I feel like im making up my symptoms in my head because of the possibility but my nipple sensitivity is VERY real and i cant fake a missed period this late..... any words of advice?!
