6 weeks, severe stomach pains when I eat

For the last 3 days I've been getting bad stomach aches when I eat to the point where I just need to lay down and not move. I thought it was just happening at night and when I ate something too salty, but it happened again this morning after having a bowl of cereal. I haven't quite started getting nauseous yet. I thought it started the other day but haven't really felt it since.

This is my 4th pregnancy and never had this before. Anyone ever experience stomach aches early on?
