You still took the antibiotics. I'm referring to a reaction to the antibiotics causing the diarrhea. Otherwise, there isn't an std that I can think of that would cause diarrhea as I stated in my first reply.
ok what if i came back negative for chlamydia and gohnnereah
Now that i think about it more, when I was treated with antibiotics for chlamydia, one of the warnings was to inform the doctor of diarrhea during or shortly after. You need to tell your doctor right away. It could be an adverse reaction to the antibiotics.
Also with these symptoms on top of the previous discharge it might be related and the discharge might not have been a STD. Advice is to see a Dr.
