Low Progesterone Cause My Miscarriage?

ReAnna

I noticed a week before my miscarriage I had just started barely spotting..but i woke up that morning and my boobs didnt hurt anymore and i had a lot fewer pregnancy symptoms. I went to the doc and had an ultrasound and baby still had a good heartbeat but i just felt something was wrong hormone wise. I asked the doc about progesterone but she wouldnt even test me for it. I feel like i miscarried because of low progesterone but i dont have any proof. What do you guys think? Is it possible i had low progesterone and its something that could have been helped?
