Whenever the doctor measures my uterine lining he says the numbers, like today was 15 and then he follows it by three letters. I can't remember what they were today, I was too focused on him saying we were triggering tonight, but in the past it was aaa or maybe like aba. I could be off on the exact order but it's definitely always a's and b's. There might be c's too I can't remember.

Anyway, my question is what the heck do those letter stand for/mean?Chat Icon
