Summarize the following:
Most women experience yeast infections now and then, and they can usually be combated with over-the-counter antifungal creams or suppositories. The treatments come in doses that are taken over a period of 1, 3, 5, or 7 days, depending on how severe your infection is. Most yeast infection treatments also come with anti-itch cream that can be used to help with itching and burning around the vulva area.  If you are pregnant, make sure to consult your health care provider before taking any medication, even if you feel certain that you have a yeast infection. If you aren't sure that what you have is a yeast infection, you should see a doctor to double check. Yeast infection symptoms include curd-like, yellowish discharge with a bad smell, itching and burning in the vaginal area, a rash on the vulva, and burning or soreness. If your infection still won't go away after a week or so, make an appointment with your doctor to get prescription medication that will wipe out your infection. You can also try doubling your daily intake of yogurt or other fermented foods to increase the levels of "good" bacteria in your body. Vaginitis can be caused by yeast infections, bacterial infections, parasites, and other causes. It's characterized by a discharge with a fish-like odor, burning and itching, and a rash around the vulva. You can buy over-the-counter creams to combat the uncomfortable symptoms, but you should go to the doctor to figure out the cause and receive a prescription as necessary. Sexually transmitted diseases such as HPV, chlamydia, genital warts, and others can cause long-term damage if left untreated. If you have unprotected sex and feel there's a possibility you could have contracted an STD, make an appointment with your doctor or go to a health clinic. In many cases you'll be able to get free testing. Many women aren't familiar with the way their vaginas look and feel, so they aren't aware when something changes. Every vagina is different, and it's important to know how your vagina normally looks, feels, and smells so that when something changes, you'll notice and seek medical attention if necessary. Go to the doctor if you notice a stark change in color, warts or other bumps, discharge that smells or looks different, or if you have pain in your vagina.

Summary:
Try over-the-counter remedies for yeast infections. Go to the doctor to get treated for vaginitis. Get regularly tested for STDs. Go to the doctor if you notice something out of the ordinary.
