    Default Progesterone Levels

    Hi girls,

    I had my progesterone levels checked and they came back at 40. They checked them at 7DPO and I'm now 11DPO. I am not on any medication.

    Has anyone else got levels back...do they have any link to if you're pregnant or not???

    Any help/advice would be greatly appreciated xo

    No link to pregnancy, it tells how thick your uterus is though. As I have had a mc, if mine was less than 80 I would go on progesterone pessaries. Now I just take them from 1dpo anyway.

    Your progesterone peaks about 7 DPO and then comes down again.

    Hope that helps

    Progesterone rises after ovulation. It is produced by cells in the ovary from the follicle that the egg came out of.
    If no embryo tries to implant in the uterus then progesterone will fall again, so endometrium will break down and then when progesterone is low enough AF will start.
    If an embryo implants then the developing placenta will make hCG (pregnancy hormone). hCG tells the follicle cells not to stop making progesterone. Therefore progesterone won't fall, endometrium will stay intact and AF will stay away and you'll miss a period (and hopefully more).

    The actual level of progesterone won't say you're pregnant or not at 7dpo, that's still in the window that the empty follicle makes progesterone without any encouragement from hCG. The level is determined mostly by the number of follicles you ovulated from. About 40 per follicle seems to be about right (from what little I've read), so if you had 80 progesterone, then you would have probably ovulated from 2 follicles so could be in the running for dizygotic twins (non-identical or maternal). I got pregnant from a fresh IVF cycle, so had many follicles and my progesterone at 5 wks (21dpo) was around 600.

    If progesterone doesn't drop over the next week then it's probably continuing to be produced in response to hCG, so you would be pregnant.

    (Be aware when googling that US and Aus use different measurements.)

    Yep, as above. Your level tells you that you have indeed ovulated. Now it's a waiting game to see if the egg was fertilized and implanted.
    At 11dpo you can do a home pregnancy test. But it may not be positive yet even if you are pregnant. By 14 dpo a pregnancy test should be positive if you are preggers.
    Good luck!
