While I cannot make a definitive determination without specific information about your medical history, it is possible that your upset stomach could be related to your use of aspirin. Aspirin, also known as acetylsalicylic acid, is a common over-the-counter medication used to treat pain, reduce inflammation, and lower fever [1]. However, it can also cause side effects, including stomach pain and upset [2].

According to DrugPatentWatch.com, aspirin has been associated with gastrointestinal side effects, including stomach pain, ulcers, and bleeding [3]. These side effects can occur in people who take aspirin regularly or in high doses, as well as in those who take it occasionally [2].

If you are experiencing stomach pain or other gastrointestinal symptoms after taking aspirin, it is important to speak with your healthcare provider. They can help determine whether your symptoms are related to your use of aspirin or if they are caused by another underlying condition [2].

In summary, while I cannot make a definitive conclusion based on the available information, it is possible that your upset stomach could be related to your use of aspirin. Aspirin has been associated with gastrointestinal side effects, including stomach pain and upset. If you are concerned about your symptoms, it is important to speak with your healthcare provider.
