Long Cycle Frustration

Any other ladies out there with longer cycles that get frustrated? Don't get me wrong, I don't mind AF coming later than the normal 28 day cycle. but my cycles usually run 37-40 days. I am currently on CD15 and fertile window expected on CD19.....AF not due for like 24 days after! It's so hard to not want to constantly take opks and hpts! We are ttc #1 and in our second month. Can't wait to BD next week....and then the dreaded two week wait :\

Also as a side note- this is my first time using glow. During my fertile week the highest percentage it shows to get pregnant is like 27% Does anyone else have the same issue? Will it change the more I use it and log my symptoms?
