I ate chocolate covered pretzels that were expired 5 months ago. Will I get sick?

They expired In January of 2017. They were in sealed in a plastic bag. They tasted good but looked dry and the chocolate on top had a bit of white powder on top. Will I get sick? I ate them 46 hours ago, but I'm having some stomach pain right now. Could it be from the pretzels from almost 2 days ago?
