Ovulation with Femara

Erin

So I’ve been running OPK’s like once a day since I started my femara doses on CD3... I’m 3 days out from Glow’s prediction (yes I know it’s ONLY a prediction and nothing solid), but I’ve yet to see any progression in test line colour. There’s a line but it’s faint and it’s not gotten any stronger really.

Is this unusual?
