Hi, I've had 2 missed miscarriages and 2 chemical pregnancies in the past 3 years. I've been to an NHS miscarriage clinic as well as to a private clinic specialising in recurrent miscarriage (CRP clinic; which I've been going to for the past year and a half for treatment). We were about to give up, but while on a trip to South Africa, decided to see another specialist here. They suggested an HSG x-ray, which has shown that I have a misshapen uterus and they believe this has caused my miscarriages. I wasn't ever offered this test, by any of the doctors I've seen.
PLEASE, if you're struggling with this issue, ask your doctor for this procedure. It will help them to see if there is anything structurally wrong, whether there is scarring and will flush your fallopian tubes (if needed). I wish I'd known to ask, so I'm hoping to spread the word. It might not give you the answers you're looking for, but I feel like, if you've suffered from multiple miscarriages, you should at least be offered this as part of the investigations.
I've added the image from my HSG - my 'weird' uterus in on the right and a normal one is one the left.
Anyway, i just wanted to spread awareness. If you have any questions, I'll do my best to answer them, but if you think it might help to give you answers, speak to your doctor about getting it scheduled
