So I just had a post partum appointment and all test were normal..Im beyond upset and hurt, I just knew there had to be a reason for losing my baby girl..Havent cried like this since the day I said goodbye😢😭😭😔..Im trying so hard to be myself again but I dont know how. How can I try again if stuff like this "just happens"..??
