But if you are having
brown discharge that seems to be alot, or smelly, or makes you
itch then please get checked. It could be bacterial infection, or an std. The pains that you are having also could be an std, or infection. Do I would truly head to the doctor.
Now, don't let all that scare you cause it can also just be normal. If you are about to start your period or just getting off of it. Still it is always better to be safe then sorry. So, if you are getting worried get checked out.
