Yes - I was diagnosed in March this year. Also known as intrauterine adhesions I believe.
It is caused by an operation on your uterus - a D&C/ERPC for a miscarriage (my cause), a C-section or other op eg for endometriosis. My symptoms were that I tracked my cycles with OPKs/BBT so knew I was ovulating, but when my period should have come I didn’t bleed. I got a bit of spotting but not much. This is because the lining isn’t able to build up due to the scars. It also means an egg can’t implant if you’re TTC. Some people also get pain as the blood tries to escape, but I didn’t. After three months of this, knew something was wrong and didn’t want to wait for NHS referrals etc as wanted to TTC again so I went to see Mr Lower - one of the few experts in the U.K. on Ashermans.
I saw him middle of the month (when your lining is meant to be thicker) and he could see it didn’t have the trilaminar (triple layer) structure, it was patchy and not thick enough. He diagnosed me there and then with it. Booked me in for a hysteroscopy under general anaesthetic for the middle of the next month (that’s when he likes to do it), and put me on high dose estrogen. I had the operation, then had a copper coil and high dose estrogen / progesterone to stop the scarring re-forming. I had a re-scan after he had taken the coil out, he felt it had been successful - back to the triple layer structure and I was lucky enough to get pregnant the next month. I’m awaiting a scan with him on Monday to know if the pregnancy is viable.
Physical side effects for me have been fine, I would never “know” I have Ashermans in terms of pain or anything, but finding out you have it and you are infertile until treated (as the egg can’t plant in the lining) is tough. Mentally it’s been a long journey and I have had to stay patient, but I’m glad that I found out three months after my D&C and had the means to be treated quickly. You’re never cured of Ashermans and the scarring could return. There’s also a higher chance of pregnancy complications like pre term birth. Financially, it can be expensive. I think the treatment with Lower is probably £6k/£8k all in including the hospital fees. I was lucky enough to have my BUPA cover most of it and I have paid £800.
If you think you have it, the first step is being diagnosed. If you have been diagnosed then it’s about getting it treated by an expert asap. Mr Lower does several operations on this a week with a very high success rate from first op. Some NHS gynaecologists never even see it!
