Guess it's time for me to post over here. I had FET on 3/9 where HCG level was low at 37, but it's been climbing steadily since then and was over 13,000 yesterday. They're still going to monitor my progesterone and estradiol, but are happy with my HCG levels. I had an US last Friday which showed a gestational and yolk sac and have another one tomorrow which will hopefully show some development from last week. It's still hard to believe it may be happening after 6 years of trying but the fatigue and nausea are starting to get real!
