I also found that it may not be an std but Bacterial Vaginosis. Which can lead to other problems so you really need to see a doctor find a way. Trust me. Go to your mom talk to her be honest. She will be mad yeah but your health will be what she cares about more. If you are not sure about that still, you still need to see your doctor. You need too..
Hey sweetie..
You really should see a doctor. Don't you have to get check ups or a physical? You should find a way to get to see your doctor to make sure that you don't have an std. Did you have sex just once or more than once? Why does your Mom think you are having your period if you had not started it yet?
