Can heartburn be one of the morning after pill side effects?

Yes, heartburn can be a side effect of the morning-after pill, which contains hormones that may affect the gastrointestinal system. Some individuals may experience digestive issues, including nausea, vomiting, and heartburn, after taking the medication. These side effects are generally temporary and should subside as the hormones leave the system. If heartburn persists or is severe, it's advisable to consult a healthcare professional.
