My dh believes

That we should only go to the grocery store once a months and try to portion out food like that. And on average we spend (150)
However I believe we need to go twice a month. Because I don't like to scavenge for food and try to make something just so I can eat. I'm pregnant and he gets all mad at me when we run out of fruit or milk and I can't help it I need to eat the best I can but not going to the grocery store is not letting me. And because of that he is like, "you can eat this you are nurturing our baby" 
And I get so upset. I wish he was more understanding. 
He is so stingy with money.
Thoughts on how I can deal with this?
