I have used progesterone 200 mg per day during last two cycles, starting two days after ovulation until negative pregnancy test... My luteal phase is 11 days and my doctor told it can be a good idea to use the progestore and make it longer, I noticed since after my ovulation in last cycle I dont have cervical mucus at all. I read this lack of CM maybe an indication of lack of ovulation... has anayone experienced something similar and managed to get pregnant? Best wishes to everyone TTC,
