No, it will not tell you if you are pg. It will tell the dr if you ovulated or not or if your progesterone levels are lower than normal even if you did ovulate. Prior to ovulation your progesterone level is low and after ovulation it goes up. To sustain a pregnancy it has to stay up.
I am curious what is the amount of progesterone injection people take? Is it 50mg. My doctor always prescribes only 25mg to me, and there is no progesterone level check. Thank you.
