Ive been having this fishy smell on my vagina. i had a yeast infection 2 weeks ago. the smell just wont go away. i am sexually active and worried it might be a sti?

It may not be a recurrent yeast infection but a bacterial vaginal infection instead. See a GYN MD or Clinic to be examined and tested for that and STI's as needed.

You probably have bacterial vaginosis and fishy smell vaginal discharge is one of its characteristics. This condition is not a STD. You should see your doctor for a correct diagnosis and treatment.
