OK so I'm almost 29 weeks and got curious so I squeezed my boob and milk came out!! Ok I know that we produce milk duhhhhh but I didn't think it would come out so soon. Like I thought it would be closer to 40 weeks. Anyways I went to try the other boob but nothing came out 😢 does that mean only one of my breast will produce????? Or is it just to early ?? I would love some advice please!! I know someone out there had been through this or knows more about it then me!
