Getting discouraged. And confused. :(

Lizz • Married to the love of my life, baby #1 due 11/28/16. :)
My chart is soo rocky. I'm on CD27 and fairly certain I haven't ovulated yet. I thought a couple of times that maybe I had or was about to, but no temperature rise. I've had seemingly fertile CM for over a week now, and I had mild cramping very briefly on Friday so I was really hopeful I would see a rise over the weekend, but nothing. No known medical issues..and really no symptoms of anything either, except that my last cycle was 76 days. I just temp, no OPKs, and I also take a prenatal and maca root. I have no idea what's going on with my body and it's getting so discouraging. And yes, I plan to see my doctor about it, just waiting until my cycle has been long enough that they will do something about it.
