Having to wait to TTC

After my second miscarriage my HCG was taking months to go back to 0, so my doctor did an HSG which showed what she thinks is either retained product of conception or a calcified polyp. She said I need a hysteroscopy to remove it. However, after a month of waiting, insurance just informed me that I'm denied coverage for this procedure. I'm so frustrated because my miscarriage was back in November and I just want to move on past these miscarriages and try to have a healthy pregnancy! Today is just an overwhelmingly depressing day where I'm just fed up with it all. It just seems like it's been one bad thing after another. Why is having a baby so easy for some people but seems to be so hard for me??? Sorry for the vent session, I just had to get it all off my chest!
