Hi all. My 14yr old daughter is having bad dysmenorrhea and menorrhagia. She is bleeding for 10-15 days. She is on the pill (started 1 month ago) and just started mefanemic acid a few days ago. Waiting for Hb check and ultrasound. I'm very very concerned that she may have endo and wonder that rather than wait for 3 months of pill to see what happens, whether I should ask for immediate gynaecologist referral. I had endo finally diagnosed aged 22. Years and years of problems and finally had hysterectomy aged 38. Just can't bear to see my girl suffering. And have another daughter aged nearly 12, worry for her too.
