Possums I know what you mean about negative thoughts. I was reading through my notes for my last transfer in Aug and I had a lot more symptoms like bloating and cramping. I've felt some slight cramping today but could be my imagination. I've been quite emotional the last couple of days.
Last time I held out from POAS until the BT but this time I think I'll try next Tues. My BT is also the 23rd and I had a 5dt.
Good luck and I hope we get BFPs for Christmas.
