@Molros Thanks! Hopefully the stitch means something good! I have decided not to POAS until the morning of my blood test. I didn't want to deal with any anxiety from POAS before then and trying to work out whether it's negative, a false negative, a false positive or a positive!! My DH also thought doing it before the BT might jinx us!
I have been really tired late this week, came home early from work today and slept. I really do hope it is a positive I don't want to get my hopes up too high though.
