For once, I am genuinely pleased to see my period show up (well, given that I've already POAS and know I'm not pregnant!)... My spotting started yesterday and today it got going proper (3 days late). I'd already done my 0.1mg downregging shot this morning, so I'll have to go to the clinic tomorrow for them to show me how to halve it using the prepared syringes I have.So I guess I'll count tomorrow as CD1... or should I count today? I read somewhere that CD1 is the first day that you wake up bleeding (which sounds so dramatic, doesn't it?). Will it make any difference? I go back on CD5 for bloods, baseline ultrasound and presumably to start my stim meds. Part of me wants to go sooner rather than later to get going with the next step... what do you think?
