I had a saline infused sonogram last week as I am undergoing ivf. I have had 2 early miscarriages and one chemical pregnancy. I wanted all tests done before I embarked on my 3 frozen embryo transfer. We didn't expect to find anything on the SIS but we did. Doctor found thickening of one side of my uterus. The same side I have been having mild pain on since mt last miscarriage. I have to wait 4 weeks now for a hysteroscopy to determine why my uterus is thickened. I am terrified its cancer! Should I seek further tests or wait for hysteroscopy?
