Hello,
Welcome to ehealthforum and thanks for writing
After a miscarriage it is common to have irregular periods and few disturbed cycles as it takes time for the hormones to come back to normal state.Regarding the pain which you are experiencing on left side could be suggestive of infection which could be fungal or bacterial in origin,pelvic infection,underlying issues as endometritis,cervicitis,ovarian causes etc.
As of vaginal discharge if it is associated with foul smell and change in colour and consistency then it might be indicative of fungal infection with a superadded bacterial infection.You need to take antifungal drugs orally along with antibacterial agent in order to treat any super added infection that might have been present.
You can consult your gynaecologist for selecting the best drug for you after proper examination and vaginal swab culture.
Mind it that such vaginal infections are notorious for recurrence and your partner also needs to be treated simultaneously to avoid repeat infections.
Till the time you see your Ob/Gyn you can do the following things-
1.Avoid irritation of the genital organs caused by various factors and wear loose cotton undies.
2. One of the things you can add to your daily diet to treat this is a banana that is dipped in clarified butter or ghee. This should be eaten with breakfast and lunch.
3. Increase your intake of cranberry juice. This juice has quite a number of properties that are good for women and drinking this juice helps with the treatment.
You can plan the pregnancy if everything is normal after pelvic evaluation.Usually during infections pregnancy should be avoided.Kindly visit a Gynaecologist for evaluation.
Take care!
