Comparing...

Betas (hcg) should double every 48-72 hours.

Last time we did IVF, my first labs were when I was 3 weeks and 6 days pregnant.  My beta (hcg) was 50. Since it was Thanksgiving, we didn't get to recheck my labs until I was 4 weeks and 4 days pregnant.  My beta (hcg) was 206.  My beta was doubling every 58.75 hours.

This time, at 4 weeks 0 days pregnant, my beta (hcg) was 354.  At 4 weeks 2 days, my beta was 690.  This is a doubling time of 49.85 hours.

Both are normal.  My numbers are much higher this time.  I know I implanted sooner this time.  I implanted on the late side last time.

Last time, the baby stopped growing at 7 weeks and I miscarried at 10 weeks.

I pray for a healthy pregnancy!  More than one doctor said there is no reason to think it will happen again.  I am going to be nervous until I get past 8 weeks.

I have a better feeling this time.  I cannot wait for the first ultrasound!  I can't wait to see the heartbeat(s)!

Continued prayers are appreciated!!!

Thanks!
