glow automatically thinks I have a 34 day cycle now.

As my periods as so irregular I've noticed that glow has changed my cycle to 34 days! It's saying I should start my period tomorrow but I don't feel like I am.
I've had loads of tests done to see if I have a hormone inbalance or anything wrong with hormones and they have come back clear, still confused.
And also last month i had a chemical pregnancy and I've cramps like I did last month and feel the same way as I did last month but I'm to scared to test 😢
