High progesterone is the main cause of
symptoms. Also, the further along you were, the longer the
symptoms can remain. It can also be due to a difficulty in accepting it. I am pretty sure I did that for a bit as well. I would see your OB and have your blood tested. After a miscarriage, not only can progesterone and HCG stay elevated, it can really throw your whole body out of whack. I wish you all the best, and again, I am so very sorry for your loss. Take care.
