I am 18 and have vaginal discharge almost all the time. It varies in amounts and thickness. It isn't always there but most of the time it is. It doesn't smell much most of the time but it does concern me that I do discharge so much. I know that it is natural to discharge some but I was wondering if I should ask my doctor about this.
Some other information if needed: sexually active, though not anymore, not on birth control, and have irregular periods.
Thank you.

Please see your doctor about this. Especially since you indicated a smell involved. There could be more problems that only a doctor could properly diagnose that you are experiencing.
