I did manage to have my transfer on 9 December in Prague, and given the recent announcements and the number of places stopping flights to the UK, I'm now even more relieved it went ahead.
Today was OTD at 13dp5dt, and the test was positive :-). I'm having blood drawn later for an hcg count, so fingers crossed it looks ok. Been having a lot of backache and cramps for the last 3-4 days, otherwise don't feel any different. No spotting or anything so far but they do have me on a really high dose of progesterone again. All being well I've got a private scan booked on 9 January when I'll be 7 weeks.
Really hope everyone else is doing ok, and good luck for those still waiting for OTD or news of embryos developing.
