hi..thanks for using healthcaremagic..
you have green coloured stools and it is not treated with antibiotics,
you are put on antimotility drugs which reduce the frequency of stools but not infection..
see your physician, and get tested with stool examination, culture and sensitivity since you are having this problem..
you need to be put on antibiotics with combination of fluoroquinolones
group drugs..and oral rehydration fluids, probiotics like sporolac, helps.. multivitamin
with zinc helps in reducing the problem..
you had spotting after 2 weeks of period.. it could be ovulation spotting..
see your physician for the dose and frequency of drugs to be taken..
all the very best.
