Will I Produce Colostrum After Baby is Born?

Megan
So, I've started lactating (at 23 weeks). I'm not sure how the body works as far as production of milk, so will I still produce colostrum after baby is born? I want him/her to get the benefits of it, but I'm too early to save and freeze what I've produced bc it's only good for 3 months. Does anyone know?!
