I asked my clinic that exact same question and they said they didn't intend to retest me at all. As you can imagine, I'm none too happy about that decision, so I'm taking matters into my own hands.
Being that I've only just moved to where we are currently living about 4 months ago, I still don't have a local Doctor. So I did a bit of research and there is an OBGYN about 20 minutes away. I have an appointment booked with him next Monday, and I'm going to ask him for a retest.
I'm not too hung up on getting retested all the time - just one more will satisfy my curiosity that things are still happening and Emby is still with us. Then a little less than 2 weeks later is my first scan, which would be further confirmation all is well.
I know I'm jinxing myself, and I'm more than happy to do so, but I really want to 'feel something.' It sounds silly, but to start feeling sore boobs or to get sick in the morning would be like a little signal to me that all is well.
Still, I suppose I am only 14 days post transfer. Under regular circumstance (non-IVF circumstances, that is!) I probably wouldn't even know I was pregnant yet.
Funny. I always thought the 2WW would be hard, and yes, it is. But then you start on the next wait, and that is even longer!!!
