Morning!
Oooh Imp your day sounds exciting! Sorry you're not feeling well still. If I was you, I would test, but be aware that a BFN might turn into a BFP later. Maybe still go drinking but maybe take it a bit easier than normal. As far as I know, you can't do much damage at the very, very early stages unless you get absolutely hammered. BUT, I might be wrong.
Grif I can't help on the early AF front as my first one didn't show for 59 (agonising!) days. But I guess it can be AF. Or it might be spotting? You might need to see how heavy it gets today to get a better idea.
Mrs V - are you using opks to check for O? (I can't remember). Hopefully your body will let you know what's going on soon. That's good news abvout your friend but understandingly a bit deflating at the same time, right? But it will happen again for you. xxx
AFM - getting some cramps today and some irritability so think AF is on her way now. My temp has been pretty steady since O as well so I don't think my body is doing anything particularly special. In a way I'm ok with this as it will allow me to focus on this job situation with a clear head. But I will of course be gutted to see AF all the same.
