HI Mel,
Cramping is normal, are you taking
Prometrium? I always had lots of side effects, felt preg, so I switched to
Endometrin which has less side effects. My side effects with Prometrium was bloating, cramping, sore breast, etc.
I think you should take two, one every 12 hours, because with only taking one, my AF does arrive, but taking two, it stays away like it is supposed to. Then you have a beta and if beta negative, you go off of progesterone and af arrives in 1-2 days.
