I am 48 year old. I have enlarged, tilted uterus with thick lining. This was examined with pelvic ultrasound and vaginal probe in January of this year. I have had 3 periods since then. One in Jan, then Feb, then April and recently last month on August 17th. I went for another pelvic ultrasound and probe test. The technician told me that there was thickening of the endomyterial lining as compared to last test. What does that mean? I have no symptoms. The period in April was heavy and painful, lasted almost 12 days. The one last month was normal. Thanks.
