Cycle length unknown!

Danielle
We are TTC for the past 3 months and my cycle lengths have gotten longer and longer! It has gone from 25, 26, 30, 38 and now I'm on day 37 with no period. I don't know what's going on is this normal? I use both Ovia and Glow with the same data and they are both different. 
​Please help! What can I do to make this easier?!
