How to hide my stomach growls in class?

Every day during third period I'm really hungry and my stomach starts growling soo loudly. Definitely loud enough for my teacher, who sits right in front of me, and the three boys around me to hear. I know it's a normal body function but no one else's stomach ever growls! I eat a good breakfast and I bring snacks to school, but no matter what I still am starving by 3rd period. Today we were reading silently for 35 minutes and i just-oh my gosh it was so embarrassing. Like every 5 minutes it would growl! Then after class i heard my teacher say to one of the guys "Was that me?"-maybe he was talking about something completely different, but I'm not so sure and now I'm so nervous to go back to class bc it was just... SO loud. Too loud for page turning and zipping up backpacks to hide.
