Do you usually have regular periods?
Do you use anything for birth control?
Is there any chance of an STD? Thank you.
I'm sorry it's taken me so long to get back to you.
I don't think you need to be concerned. Most likely your bleeding is related to your hormones being out of sync for some reason.
At your young age and with fairly regular periods before, there is almost no chance of cancer. An STD can cause irregular bleeding, but that seems unlikely, and this type of bleeding doesn't seem like it would be from an STD.
The bleeding may take care of itself, but since it's been going on for 2 weeks, I would make an appointment with a doctor to check it out. Assuming that your exam is normal, some progesterone pills will likely stop the bleeding. Best wishes.
