I've tested negative for both chlamydia and gonorrhea yet i have the symptoms. I've been to several different walk ins, been prescribed a shot and two pills which i took immediately on one occasion. when that didn't work i went back and was given a shot and prescribed doxycycline 2 times per day for ten days. unfortunately i was on vacation and had trouble taking the doses exactly 12 hours apart, however i did take 2 doses per day except for one pill which i threw up. while on the medication the discharge stopped... 2 weeks after treatment it has returned and i am now wondering if i should go back for a second treatment or if this may not even be chlamydia.
