Having period cramps a week before period?

Emilie • Mom of a baby girl born November 4th 2016 after ttc 18 months. Baby #2 due Sept 19 2018 :) 💕💕💕 I'm a french canadian 🇨🇦 so sorry if my english sounds a bit crappy sometimes. I'm trying my best !

Its been 2-3 days that i feel like i’m having period cramps and back aches.

But af is only due in 8 days

I can’t remember if i had this at my first pregnancy.

Who had that and had a bfp?
