Hi Karentia,

If it helps I'm in a very similar situation. My last measurement was about 27.5mm (my lining was normal in December) and I recently went in for a hysterscopy (sorry for spelling I'm on my phone) as they wanted to see what was happening.

The important thing to remember is that, at your age, it's highly unlikely to be endometrial cancer. There are a myriad of conditions that can cause the lining to thicken, such as endometrial hyperplasia, polyps and fibroids. Hormone imbalances can effect lining and the point in your menstral cycle also has a massive effect.

I imagine they are just keeping an eye on your uterus out of an abundance of caution. The great thing about the uterus is that it can be very easily removed and not significantly impact our daily lives, so if they find something they don't like they can act before it becomes an issue.

Let me know how you get on at your next scan, but from everything you've said I doubt there will be any significant problems.

Best of luck,

LF
