How long is your leutal phase?

Kim
I'm using 2 different apps and have 2 different days for next expected period... I didn't O (confirmed by opk & O pains) til CD 20..... This is only my 3rd cycle because I had been bf our 16 month son... So according to one app my lp is 8 days but Glow says 11... Either way it's still pretty short 😞
