So.....silly me went on another test splurge with an exhausted fiancé in tow. Decided to try the CB early digital as it said you can test up to 5 days early and I'm 4 days before AF. Had some faint lines on the FRER and thought bugger it. Came up negative. Almost in tears we decided to read more into the leaflet. It's a bloody HCG strength 25! FR are 6! How the hell can they sell these as early! The other digitals are the same strength and don't sell for early testing. It's awful how brands target us in the way they do. Absolutely gutted as thought they would put me out of my misery
