Hi there, you need to see your doctor for a prescription of antibiotics. All your symptoms point to thrush (Candida). Do not have unprotected sex during antibiotic treatment as it can be tranferred to a partner. If you have a partner now and you have had intercourse whilst suffering these symptoms, he too needs to go with you to see a doctor for antibiotic treatment as Candida can be spread from person to person, with men not necessarily acquiring the same symptoms as you which is why this situation keeps continuing.
Go to a doctor if it is an infection or an STD you need antibotics.
If you're pregnant, these symptoms arent uncommon.
If you're not, then you should see a doctor.
Sounds like a UTI and/or a yeast infection. You'll want to get to the doctor in case it is a UTI because if it is you'll need antibiotics.
