If you stop pumping for 3 days after giving birth a week ago will the milk go away?

My pump broke and i cant get out and get a new one til sunday, my baby wont breastfeed because she wont latch on, so ive been pumping at least 2ounces a day to feed her plus formula. I really want to keep pumping and giving her breastmilk anyway i can, but now i cant get a new pump since i cant drive for another week and my husband doesnt come home for three days... So i was wondering if my milk will dry up by then?? And what can i do to preven it from drying up??
