Precious pregnancy. Need some suggestions and assuarance

Sana
Hello ladies! I am week 29 from my LMP I went for my regular checkup yesterday and doctor said she feels I have more than adequate liquor. Any idea why that happens or what implications can it have on my baby? I am really worried. I had blood sugar raised at week 25 but with diet management that has become normal. I have been on metformin 500 since 2 years( just an additional info)
