accidentally ate expired fruit cup

And now I am freaking out. I just bought them on Tuesday from the store so I didn't think twice. Ate one for breakfast then this evening I went into the fridge this evening and noticed that another one from the package looked a little dark and I look at the date and it expired at the end of February! I threw the rest away immediately. Everything I have looked at says I should be okay and that they should be fine 4-6 months past expiration. I didn't feel sick at all and baby has been moving around like normal. Tasted fine this AM. I'm being paranoid, right? I have just been so careful about following all the rules... not eating anything from delis, soft cheeses, alcohol and now this 😩
