after baby I have yellow smelly icid/bitter discharge?

Hi,
Welcome to ehealthforum,
Foul smelling vaginal discharge, altered color or consistency of vaginal discharge could indicate vaginal/vulval infection. Visit your doctor/gynecologist at the earliest for examination and vaginal swab/smear test (done on the discharge) to identify the causative agent. Get started on treatment as appropriate (based on examination and investigations results) to help you control the symptoms. Consider requesting for prescription of a Probiotic (to be used after you finish with taking the other medications) to restore the normal vaginal flora to minimize chances of re-infection/repeat infections. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle. Avoid vaginal douching, use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. Avoid sweat accumulation in the area. If infective cause is detected, and if you are sexually active, it is important to get your partner also treated simultaneously to prevent chances of re-infection, and avoid having intercourse while being on treatment.
Take care.
