Slower Embryo Growth Question

babymine1985

Had my FET on 2/28. Had first u/s on 3/24, when dr said embryo should be 6.2 weeks, but measured at 5.6 weeks. 1 week later, 4/1, embryo measured at 6.4 weeks, but we saw the heartbeat at 120 bmp. Dr wants to see more growth and hear the heartbeat in 1 week from now. Any similar experiences??? This stuff is crazy-making, I tell ya!!!
