I'm so confused by my doctor's instructions for progesterone. I am taking it for endometriosis. She wanted me to start taking it at the onset of pain in my cycle and then take it continuously every day until I got my period. Last month I never got my period and figured I did something wrong so I stopped taking it and AF arrived.

This month I called the nurse to check with the doctor's instructions. She said to take it every day, even if I don't get a period. She said this would not interfere with trying to get pregnant and would actually help. This makes no sense to me.

What were your instructions for taking progesterone (either for endometriosis or not)? Do the instructions my doctor gave sound "off" to you? Also, did you have side effects taking progesterone?
