Let’s get straight to it: UTIs (urinary tract infections) are a pain—literally. But can they also mess with your cycle and make your period show up late? Here’s what the research and real-world experience suggest.
Can a UTI Really Delay Your Period?
Short answer: not directly. A UTI doesn’t usually affect your hormones, so technically it shouldn’t alter your menstrual cycle. But life (and bodies) are messy.
Here’s why it might feel like your period is late after a UTI:
- Stress: Being sick can spike cortisol, your body’s stress hormone. And stress can absolutely delay ovulation.
- Antibiotics: Most don’t interfere with your cycle, but they might mess with how your body metabolizes other meds, especially hormonal birth control.
- Dehydration or fever: Being run down from a UTI can make your body prioritize healing over ovulation.
