Help!

Ok. So I’m on cycle day 30.

I have 29 day cycles - every month without fail.

Fertility Friend says Af is due today.

Ovia says af WAS due two days ago.

Glow says af is due in two days.

Man I am fucking confused.

I’ve taken the really cheap dip strip tests that are 25miu but I can’t see shit on there at all.

Now Ovia has always been pretty bang on for me, so should I spend the money on an FRER or not?

Arggghhh.

SO HELP ME OUT GIRLS! What would you do?
