Accidentally wore my sister's contacts :(?!

I made a stupid mistake of accidentally putting on my younger sister's contacts before going out to hang out with my friends. We have the same contact case but mine has a sharpie with "L" and "R" on it for left and right. Her prescription is a bit higher than mine since she has worse vision than I do. I noticed my vision started to get a bit blurry but thought my contacts were just bothering me a little bit cause it went away for awhile. But my sister texted me saying I was wearing hers. I took them out and threw them away, and I have worn them for about 3 hours. My eyes are a bit red and I have a little headache. Will I be okay?
