This month I was prescribed progesterone supplements to take in the second half of my cycle after two back to back chemical pregnancies. I’m super worried about misjudging my ovulation day and starting it too early. My cycle has been a bit different after my chemical last month and I feel like my ovulation symptoms ramped up much earlier than normal, which is leaving me second guessing all my normal fertility signs. Does anyone know what happens if I start it too early? Would it prevent ovulation or not really have an effect?
