discharge of any kind right now is likely milk, it'll become more milky and golden the closer you are to delivery. it is suggested not to mess with your supply until after birth. your body will make the perfect amount of colostrum for baby then move to milk. only 5% of women literally cannot breastfeed. most moms who think they can't actually can but have incorrect information or a lack of support.
For now, maintain a healthy diet, adding whole oats is helpful as well.
After baby you can nurse on demand (every time baby cries) and pump after to build a higher supply if you want to nurse as well has bottle feed.
hope this helped
