My dear you should have a STD's or another kind of Virus (isn't bacteria) there are many reasons for you can have it, the more scare thing for me its a bug.
The vagina and all the female reproductive organs, with the humity (you know all the girls we are lubricate in this area), so its a good enviroment for a reprodruction of Virus, you should have be careful because they most treat you right away in E.R.
Your period isn't normal really you should fly and jump to a E..R. at soon its possible, really if you let wait more time, the bug (that's is probably make the main damage inside you, could reproduce or .........something worst.............can really makes you more sick, than you are now.)
Maybe if you are sexual active the type of infection that you have its one of the hard ones; don't worry with a proper care can be exterminate.
This type of bug , really can make a big damage, special in the cervix or uterus, or even your ovaries.....I'm sure they will give you in the hospital a very hardly and strong antibiotics...
You maybe have something call Trichomoniasis, its a infection transmited sexually, and its a cause by microscopic parasit, usually its itchy and painful , color yellow to green, but in your case could be another bug or disease you may have to give you the period color orange blood and with the bug.
Really GO NOW AND FLY , JUMP TO E.R................DON'T WAIT MORE TIME.................COULD BE A DISASTER.
I'm not a Doctor to accure what you really have, but my career has to be involve with medicine, so please follow my advice............go for medical help.
GOOD LUCK,MY DEAR FRIEND!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
