Hi Flopsy, try not to work yourself up too much, great you have the scan date, shame you have to wait, but it will be so much more reassuring next week when you want to see the hb anyway,otherwise you would still worry.
Sounds like at 5 weeks 5 days, theres still going to be lots of nestling in going on in there and so you wil get tiny little bits, as long as it's not bright red and lots, then all should be well. I bleed with Devon all tri1 , browny old blood , every time I wiped, I was a wreck, but all was well. Good luck on monday, try to keep busy this week and it will fly
