Hi Camille,
I just wanted to check in to see how things were progressing. I also had invitro treatments and am currently 6 weeks pregnant. Congrats to you!
Your question is a good one, and I would refer you to this website which lists the appropriate HCG levels based on your week: http://www.americanpregnancy.org/duringpregnancy/hcglevels.html
According to this, your numbers are fine and still in-line with what is viable.
One correction I do want to make from the other post however. Just b/c the embryos were placed in our uterus does NOT mean we can't have an ectopic pregnancy. There's still a chance that the embryo can float to your fallopian tubes- it's not officially viable and stable in your uterus until your hormone levels are where they should be. In general you really need to hang tight until your ultrasound.
Although my levels are different, I too have anxiety waiting for my ultrasound which is on Mon the 15th.
I hope some of this information was helpful to you.
Stay in touch,
Marnie
