I craved chips my entire pregnancy dr said it was fine just don't binge eat them!
As long as you aren't eating tons of salted foods the rest of the day, you should be fine. Drink lots of water.
One bag a day probably wont do much to you. I think you're okay.
I mean it's not going to kill you and I ate hot cheeto fries with a dr. Pepper when I was pregnant with my daughter almost everyday, but it's not the best thing to do. Too much salt, then there's always the risk of developing pre eclampsia and then enclampsia. Just try to cut down.
