Kat have you had your progesterone levels checked?
Kat~ Im so sorry That is so frustrating that your doctor isnt willing to help you. I was told with my m/c that it was likely caused by low progesterone so tell you what, you give me some of yours and we will both be set. Hopefullt everything turns around and you get your BFP. Some women get theirs weeks after AF.
Kat - happy birthday to your DH!
When I had a chemical I got a faint but definitely there line on a frer.
I could be wrong but I think with a chemical you would have gotten at least a faint line at some point?
I hope that you either get a BFP soon or at least some answers!
