Breast feeding questions??

Mikayla • I'm 23, married for 4 years, we have a beautiful 2year old little girl! she is our universe!!!! I'm a cancer in a home with two Capricorns!!!! Baby #2 due may 2019!

So I'm right at 29 weeks and my doc keeps asking if I'm leaking or not yet and says by now most women are just a little.... I'm not leaking at all and haven't had sore breasts or anything. My mom was never able to breast feed and of her three kids bec her milk never came in and my sister barely breast fed her second baby for 4 months. They said me having a larger chest anyways and my mom and sisters history with it that I may not be able to either...

I do want to breastfeed but if I'm not able to I'm completely fine with formula feeding and people tell me I'm a terrible person for even entertaining the idea of not even trying bec I most likely won't be able to anyways...

What do you other ladies think???? Should I try like I planned or no?? Should I be leaking or anything by now?
