Welcome to the forum. I can understand your concern for your health problem. I recommend you to visit a gynecologist and get clinically examined. You have not mentioned the details of the symptoms that is the causing you such upsets.
You should get urine ( routine and culture/sensitivity) done. Depending on the severity of your symptoms and diagnosis you will be advised ( VDRL
or Australia antigen). You should get treated properly before marriage else you may infect your partner. Don't feel shy and get treated. You are in need of antibiotics.
Take high protein diet, food rich in calcium, you may take some antioxidants
to help yourself with your general health conditions. Take plenty of water, do not hold urine for long. Have an antiseptic wash whenever you go into the rest room. Improve your toilet habits, keep yourself hygienically clean.
Enjoy good health, take care.
