Hi, 

First time posting. 

For around a year or so i have had really heavy and painful periods, so i went to the doctor who referred me for an internal scan. My scan showed my endometrial thickness was 15mm so i was referred to have a biopsy taken. 

The biopsy came back with no abnormalities but i was referred for another internal scan which has shown my thickness has changed to 18mm now. Doctor has said they will see me again in 6 months. But i feel like thats 6 months of worry rather than 6 months of reassurance. 

Should my lining be increasing in thickness that much in the 3 months between the scans i had?

Can i request any other tests? Im constantly worried that all i have red online has said the thicker the lining the higher risk for cancers.
