Hello, I’m in a similar boat and saw your post as am awake at 1.12am having a panic attack and not able to sleep. I started bleeding last Friday after nearly 15 months of no periods. Today my ultrasound showed a thickness of 4.8 but no fibroids or polyps. I saw the gynaecologist afterwards who attempted to do a hystroscopy to do a biopsy but couldn’t due to previous ablation I’d had 10 years ago so I’m now waiting for a date to have it done under general anaesthetic. I feel drained and scared. Google is not a good place to be and I wish I could stop but I’m trying to find any reassurance I can. Good luck with your tests.
