...also eating a diet high in sugar can cause you to feel hungry.
Look up some stress management techniques. Find, and practice, one that works for you.
CHANGE YOUR DIET AND INCREASE YOUR WATER INTAKE!
I am no doctor. It sounds like two problems that can be made worse by your choice in diet. If it is a yeast infection, sugar will make it worse. The pasty stools you are having should hopefully be fixed by consuming plenty of water and making healthier food choices.
If you are sexually active, you may have Pelvic Inflammatory Disease, or something sexually related. Yeast infections usually respond well to eliminating sugar, better diet, and some over the counter Monistat/Miconazole. I sometimes use those and then if it doesn't get better, I go to my doctor.
You should visit your doctor and get qualified medical advice! Some STD's will reek havoc on your entire body and can even lead to not being able to have children. It is not anything to put off.
you should see a doctor, stop soda for sure... The pelvic pain is a sign of infection. Some women get infections there just due to an overgrowth of natural bacteria, then there is the other handful of things it could be. You definately should go to a dr immediately, that is not normal and you surely do need some antibiotics... hope all gets better! But do not wait until October thats CRAZY!!
could be numerous things, but sounds to me like you may have either a urinary infection or a pelvic infection, go to a clinic if you cant get seen by a doctor as if it is any of the above you will need antibiotics, either way you have to get this sorted, good luck
