Anyone experienced chest pain at second trimester?

It could happen if you have a very bad heartburn. I've experienced the pain many times on my left that I couldn't even sleep on that side & it takes days to subside. My trick is not to eat after 6 or 7pm so you can have a peaceful sleep with no heartburn. If you feel hungry just snack on some biscuits and water or milo or milk. Whatever that is light. You can also ask for some antacid from your gynae.
