The ultrasound went well. bub has a heartbeat of 120bpm. it is measuring 4 days behind dates which is concerning me a little.  Betas today were greater than 225,000 and progesterone was 66. the progesterone has me worried as on last tues it was 75. i have more bloods on thurs. if it drops below 60 i start the progesterone pessaries. and my doc tells me the danger zone is below 30. I have another scan on monday and i'm counting the seconds. both my angels hit trouble in week 8 and i am scared stiff this week.
