Infertility

My progesterone levels were 0.7 this cycle at CD21 so my doctor is referring me to an RE(reproductive endocrinologist). According to my doctor's nurse we should get an appointment rather quickly. I'm expecting a phone call today with the details of the referral. According to my doctor the RE is awesome, will listen to our concerns and questions and she does a lot of testing to figure out what the problem may be. I pray we have answers soon.
