With my last I tested when my period was 3 days late so roughly 17dpo and I got a BFP straight away but it was twins!
I'm going to wait until morning and use my FMU. Going to buy another batch of FR and some Pregnosis ones as well!
Fingers crossed, I'm really trying to not get my hopes up.
Not sure whether to tell DF about it because he'd be extremely disappointed if I wasn't.
