So sorry to hear your news bobo 
I hope all works out well sweetpea
I also crochet! I'm not very good though, but I've been practising!
I had my scan today, same doctor. She said it's still measuring as 4-5 weeks
which is what she said last week. But it's grown (from 3.3.3mm to 14mm) and there was a visible yolk sac this time so that feels reassuring to me. Even if they say it doesn't correlate to my bloods & dates. By LMP I am 7+1 but I personally think 5+2 so I am sticking with that! She wants me to come back for a rescan in 2 weeks.
