Hi, Welcome to HealthcareMagic Forum.
You should be seeing a Gynecologist at the earliest and get yourself examined to rule out if you have a Pelvic Inflammatory Disease
(PID) as your symptoms suggest this. It is highly unlikely that is codom is left inside your vagina for such a long time.
See your Doctor at the earliest, once the diagnosis is confirmed, the treatment will depend upon the cause. You will require antibiotics and antifungal drugs.
Also get your Blood Pressure tested.
Stick to your treatment plan and go for regular follow up.
Wish you Good Health.
