Hungry or starving?

Does anyone else get woken up by the pains in your stomach of being hungry?

I know I should be eating healthy and all for the baby, but to have little to no money to buy the proper foods I have to make way of what I eat. I wake up every morning out of a dead sleep feeling like I haven't ate for 5 days (yes I know what that feels like) I just know the baby is sucking everything out of me and taking all the nutrients that I actually do have in my body. I just don't know if I am hurting baby by laying in bed not eating right away :/
