Endometrial scratch and copper IUD following 7 miscarriages

[MF18]

Hi. I have recently been seen at St Marys in London following 7 miscarriages in the past 2 years. They have booked me in to have an endometrial scratch and copper IUD fitted for 1 month. I just wondered if anyone has had success after this procedure following so many losses. We have lost all between 5 to 6.5 weeks apart from one we had a missed miscarriage at 13 week scan no heart beat and baby measured about 9 weeks. Needed ERPC after that loss so they are looking to see if there is any damage to my uterus from previous surgery and will fix when I'm under if needed. Just wondering if anyone has had success following the scratch. TIA.
