The first cycle on progesterone was great. For once my TP was clear a whole cycle (I have Luteal Phase Defect and start spotting CD 8ish).
This cycle I started spotting at CD9. Boooo... I have a call into the doctor. Does anyone know if breakthrough bleeding means the progesterone isn't working for lengthening the Luteal phase? Or are there other reasons for BT bleeding (besides IB which I am not very hopeful of).
