I had a MC at 8 and a bit weeks in June, and have had no luck ttc since. I've gone to a private clinic and have just had a mid-cycle scan and the radiologist could see some fluid near one of my tubes. He said it might just be a blood vessel but could also be hydrosalpinx, especially as I had an emergency operation to remove my appendix a few years ago. He's recommended I have an HSG to get more info. Can anyone tell me about the risks of an HSG? Im worried about having an invasive procedure. Also, does anyone know what the issue with hydrosalpinx is? Does it just mean that one of my tubes is blocked, or can it be a contributing factor in miscarriage? Many thanks for your help!
