I had 4 early mc, never saw heartbeat, all between 5-6 wks, had all tests after 2 mc,
my clinic puts everyone on those who have early, unexplained recurrent losses but I was only on those drugs after m/c 4 though then I had IUI and stim meds and had twins
I did have a uterine septum removed but had 2 mc before and 2 mc after it was removed
