Missed Period all BFNs

Brooke
Well tomorrow marks me being 4 weeks late for my period and all I've gotten is BFN after BFN
Some background- I'm 27, been on BC since I was 15. Recently stopped BC (on Nuva ring since age 19?) in March to start TTC. I've had 2 periods since then, one cycle 36 days and the other 38 days. Now I'm at cycle day 64. Never been pregnant. 
I had a lot of cramping, acne, and headaches. 
I'm assuming my hormones are imbalanced and/or my prolactin levels are high (always had white nipple discharge)
Anyone have similar experience?
Going to the doctor today and will update!
**after doctor appointment update** Negative urine test at the doctor, as expected. 
Doing a blood test tomorrow as well as checking my pituitary, thyroid, and Ovaries (via blood tests) will update with results after my appointment on the 24th!
