Leaking and breastfeeding?

Hollyanne
I am 34 weeks and this is my second pregnancy. With my first my breasts were leaking a lot earlier. I have yet to have any leakage this time around and am worried if this is going to affect my milk coming in. I already had problems with milk supply with my first, i wanted to try harder this time, breastfeed longer than 3 months, but i am getting really worried.
