Came in at 2544 at 17dpo (or it could be 18dpo, since the hatched blast was really a day-6 blast). They were looking for 1348, so this is high. Twins, perhaps? We'll find out at the ultrasound on 9/29.
I'm calling a genetic counselor today to investigate the tests we may need (there are some issues on my side of the family, but the REs didn't want to do PGD because it hasn't been shown to improve pregnancy rates in situations like mine).
Holy moly. This train has left the station. We'll see if it crashes along the way, but for now it seems to be plowing ahead. No symptoms to report yet, just some vague cramping.
