Well done for exclusively breastfeeding your little one. Breastfeeding on demands with correct latch helps to drain breasts completely.
Breast milk production works on demand and supply method. More you drain , the more milk you get. Make sure to drain one breast completely before switching to the other breast.
You should have a well balanced diet and have plenty of liquids in your diet.
Don't worry if your baby is passing urine at least 6 to 8 times a day.
Please consult a Lactation Consultant in person who can assess your milk supply and help you.
