Is yellow-green discharge normal before my period?
Yellow-green vaginal discharge is not a normal part of your menstrual cycle and often signals an underlying issue, most commonly an infection such as trichomoniasis, bacterial vaginosis, or another sexually transmitted infection. It can also point to irritation or inflammation that requires medical evaluation. Because the causes vary widely and some require prompt treatment to prevent complications, identifying the source early matters. Take a free, instant, online symptom check to better understand what may be causing your discharge and to help you decide on the right next steps.

Explanation
Your body naturally adjusts the amount and appearance of vaginal discharge during your cycle. Many people see clear or white discharge that sometimes becomes thicker.
However, yellow-green discharge is not usually part of the normal changes that happen before a period. It can indicate that something else is happening, such as inflammation or an infection.
Infections may cause discharge that is yellow or green in color along with other signs like a strong odor, itching, or irritation. In some cases, cervical secretions or mild irritation might change the color of the discharge, but it is important to look for additional symptoms that signal a problem.
If you notice extra discomfort, changes in odor, or other signs, you can use Ubie's free AI-powered symptom checker to help identify potential causes before consulting with a healthcare provider. They can perform an evaluation to determine the cause of the change and help decide if treatment or additional tests are needed. Staying aware of your body's signals is important, and addressing changes early helps keep you healthy.
