Cuddlepie - OK, I sounded confident 10 mins ago, but now the panic is already sinking in. Clinic said estrogen was "a little low" and last time I had an ultrasound scheduled for Thursday (at this exact point - the days are the same IYKWIM) and this time they are just giving me a BT. But I know they do not do US on the weekend. Do you think that sounded like a low number?? Here comes that damned rollercoaster AGAIN!
