Hi, I'm on CD33 with no sign of impending AF. I think I OV'd about cd 17-18. I've done loads of tests, l thought I had a shadow of a positive 5 days ago, but all BFN's since so I assumed it was chemical. Upon reading though, I need a period to prove it has been a chemical. I feel a bit in limbo right now, has anyone had faint BFP, then BFN's and then no period? I don't know what's going on at all :(
