Sounds the same as me but my womb showed an area of 19.5 mm which is very thick apparently. The surgeon didn’t say anything other than I needed the coil which he fitted there and then. It’s been almost two weeks now and no result as yet. I had a bad back with a cough last week and I totally convinced myself I had cancer which had spread to my lungs. I think I suffer health anxiety which has been exaggerated by Dr Google.
