ok thank you! The doc did say that I "should" wait a few cycles b/c of the chemical pregnancy but she said it is not "necessary", just "recommended". She is not an RE, she is an OB. Everything I have read says to start the progesterone after O so that is most likely what I will do. I almost always O on CD 18 so I don't want to mess up my cycle altogether.
I feel bad going against doc's orders but I honestly am not sure she knows what she is talking about.
Did your doc tell you to stop TTC for a few months while you are on the progesterone so she could treat your LPD???? If not then I would wait until after you ovulate to start taking the progesterone.
