Alittle - I remember reading somewhere that sometimes a little blood vessel can burst and cause some bleeding. At least scan showed nothing wrong going on and all you have to do now is wait, shouldn't be too long now.
JFB - sounds like H is nearly ready for TT, I think I'd start with poos first by putting him on the potty when he is about to poo and see what happens. If he does one then tell him it's better than doing it in his nappy and he might get it...hopefully, alot easier said than done sometimes.
Thank goodness for air conditioning, I would have gone out of my mind yesterday if I didn't have it.....JFB how did you go????
