My FET failed may 13, I was told to stop medication, I'm waiting on my period to come which was suppose to come may 14th, the nurse told me it would be delayed, I've gotten the worst cramping, yesterday morning I was balled up in my bed it hurt so bad, I took something for it & it was OK but I kept feeling a weird cramping feeling randomly all day but it didn't get bad again & still no period yet, if the pain is bad now, how is it going to be when it actually comes.
