Mortgage options before fixed term expires

Mortgage reality check – only paid off 17k in principal after 2.5 years.

What are my options?

396k mortgage, 30 years, 4.4% interest. Fixed term expires Sept 2026.

After paying ~1,950/month for 2.5 years, my principal has barely moved – 17k down, ~60k gone to interest. Ouch!!

I have ~50k in savings (post emergency fund) and want to repay some of my loan back when renewing the fixed term. I am hoping that i will get better interest rates now. What are my options and how to start?

Appreciate any advice!
