Hi girls.
So my cycles vary from 30-36 days. Last cycle I'm sure was 36 days (based off when my peak was). I got a BFP which ended in cp so I can't be certain. I have 8 digital OPKs left and wondering when to start testing with them this cycle? (I want to be sure I have enough to reach static smile). I also have cheap opk which currently have a faint line which has got slightly darker the past two days. When should I start to digital test? I'm worried I'll start testing too soon or too late? X
