I ate something disgusting?

I bought some rib-eyes last week the date for expiration was today but I put them in the freezer about 3 days ago and when I thawed them out today I thought I smelled something bad. I put them in the oven and as they cooked I wasn't sure so I told my husband to smell them and he said they were OK. Well my husband and son both ate theirs and said that it was very good I got halfway through mine and it was good until I took a bite of something that just tasted rancid. I spit it out immediately and walked to the bathroom and threw up. That was roughly around 9 hours ago. Now my belly is gurgling pretty loud but I am not feeling sick other than when I recall what happened but that is just memory not real sickness I think. Do you think I should do anything or just wait?
