Is this normal with the stomach flu, Way embarrassing!?

So two days ago I had the stomach flu. I woke up and puked almost 20 times in 5 hours. I was so weak and exhausted so my husband took me to the instacare where they gave me some anti-nausea medicine and iv fluids to get my hydrated again. Well, yesterday I was feeling a lot better, so my husband and I went to dinner at a Japanese steak house. I had teriyaki noodles with sesame seeds. After I ate, I had the worst stomach cramps and I needed to use the bathroom but couldn't. Finally this morning, I was able to go (it was diarrhea) and noticed all the sesame seeds in it, as well as a noodle. Now, I am pretty sure this was not a worm. It was as long as a noodle, and my stools had the same color as the noodle blended in it. Is this normal? thanks,
