Clearblue and cheap sticks



Can anyone give me advice ,

I am only Cd7 of a 31 day cycle, but this month I’ve gone from 36 days to 31 days so decided to start checking my ovulation earlier than usual

I use clearblue and cheap stick along side eachother and yesterday both were low now today clearblue has gone to high but cheapy is still low or non existent, the cheapy ones I’ve had a peak the last 3 months and it matched with my clear blue last month!!

Also surely a high result is not possible this early on in a 31 day cycle??? ( last few months I’ve ovulated around day 16-18!)

Can anyone help please!

So confused and worried I’m going to miss my peak!!!

Thank you 😘
