Hi,
Welcome to Healthcaremagic,
Your burning during micturition and frequency of urination points to wards strong possibility of UTI (
Urinary Tract Infection), this infection could be after your sexual activity.
You should consult a doctor and get Urine analysis R&M with bacterial culture and sensitivity, and take plenty of fluids and water to dilute and flush urine, and doctor will prescribe specific antibiotics and if required after culture report may be switched to more suitable drug.
If you have pain can take a
paracetamol tablet to reduce pain,and fever.
Taking cranberry juice and antiseptic like Pyridium may help.
You have mentioned taking I pill please understand this drug is
emergency contraceptive pill and not regular contraceptive pill and should not be used for purpose of routine contraceptive.
Please use
barrier methods which protects from unwanted
pregnancy as well as sexually transmitted diseases.
Take care
Good Luck
