you can bleed more sometimes due to irregular menses because of hormonal (chemical) levels of your body and its effect. but you can bleed also due to cervical erosions and infection there. i personally never recommend tampons. because your menstrual blood contains some bacteria and pathogens which can infect. and when you use tampons due to the collected blood it gives a media to growth of that bacteria. the body can resist infection up to a limit and as the limit crosses you get signs and symptoms of infection for which you may have to take treatment. now in your case foul-smelling discharge and discoloration of the discharge are the signs of infection. now i have to see actually where the infection is. so best consult your nearby gynecologist. let him see where the infection is and what type of discharge actually is. and if required then send the discharge for examination. by this we will know the type of infection and can give treatment accordingly. most probably you are having history which seems to be likely bacterial vaginosis. it is a mixed infection. you will need to take the antibiotic course for 10 to 15 days and follow some precautions to avoid recurrence. now as far as antibiotics are concerned i have to see the first type and nature of discharge and smell. so better get consulted nearby for that. kindly keep up the following precautions: do not use tampons. use pads and change more frequently during menses. keep the area around the vagina as dry as possible especially during menses. change underwear more frequently if required. use cotton underwear if possible. drink more water as your urine becomes clear. do clean vaginal area and immediately after urination and after every time you do sex. these will help to avoid recurrence. and firstly complete the drug course to completely eradicate the infection. for further information consult an obstetrician and gynaecologist online --> <link>
