Hi. I've heard from other IVF'ers that FET embryos and blasts can implant a bit late but haven't been able to find any information on this.

I ask because I had an FET two weeks ago and my HCG level has been low, although it seems to be doubling normally and picking up speed (see below).

9dp5dt: 45
10dp5dt: 61
13dp5dt: 196

Is the slow-to-start FET just an IVF urban myth or does it really exist? Does it bode poorly for the outcome of my pregnancy?

Thanks so much for any info anyone can provide me!

Embryos cannot survive long in the uterus unless they are implanted; therefore the idea of slow or late implantation doesnt seem logical.  Implantation can be aberrant if the embryo is abnormal; this may contribute to why some abnormal pregnancies are associated with lower serum hCG levels or inappropriately rising  serum hCG levels.  The good news is that your hCG trend appears thus far right on track.  (The number should double every 2 to 3 days.)

I've seen many women on this board say their betas started slowly and then they went on to have healthy pregnancy. Stay positive and as the doc says your numbers are rising appropriately and that is all that matters at this point. I wish you the best of luck!
