Has anyone had a hysteroscopy?

Background story I have had three miscarriages in one year. It has been six months since the last one. I have had so many tests done and in all everything looks good. 
My infertility specialist said it was the last test she would recommend doing. She recommended this, because she notice that in all of my scans my uteran wall was thick. Anyway as I was waking up she told me she removed multiple polyps and found that my cervix was tight, which she also said she fixed. 
Has anyone gone on to have polyps removed and cervix loosened and had a normal pregnancy? Honestly I would just like to hear your experiences. My hubby and I are excited to started trying again!
