Just started using OPKs after a couple of months - had a MC in January and this is my first try with OPKs.
Using Clear Blue Digital ones and they are wrecking my head. Day 1 I got a Low, then next day Peak (no High in btw), then day after another Low, then today another Peak. Was getting fed up so bought additional tester and tested same sample again after getting another Peak - and this one said Low!
I don't know what's going on, and it's very upsetting - any insights appreciated!
