Hello. I m 19 day after embryo transfer. Day 12 ChatDoctor was 86. Day 14- 167. Day 17- 467. Is this a good grow? 17 day it appears a little bit brown blood, 18 day also, today it was only morning. What it can be? And for ChatDoctor is it good numbers or they are low?
Hi apparently there is no reason to worry. In normal healthy pregnancy Chat Doctor level almost doubles every 48 hours and your test results are showing that.  They are not low. I don't think you should worry about the little brown discharge you are having with no other complaints. It seems like implantation bleeding (bleeding occurring as the embryo attaches to the uterine wall)Relative an ultrasound after one week when you should see a baby sac. Good luck. If you have any further concerns do contact me through Chat Doctor.
