I just don't understand...

My partner and I have been trying to conceive for almost a year and a half now.. I finally went down and got all my levels tested and my results came back yesterday. Doctor says I came back super low for my progesterone levels. Has anybody had this problem? She said it is possible for me to eventually get pregnant but I have a super high chance of miscarriage because my body doesn't have enough progesterone to carry a child. I don't know how I feel. Just numb. I try to explain to my family and friends but it's hard. This is what I've always wanted. I was born to be a mother.
