My mum had this and her levels came back normal so they sent her for an internal scan. Her womb lining was thick (6.5mm post-menopause) we're waiting for results on the biposy taken x

Thank you for your reply. 

My Dr sent me for the bloods and arranged a scan on the same day.. got my blood results tomorrow. Just got to wait for the scan to come in the post now. 

I hope your mum is ok and it's nothing sinister, x
