Yeah, I'm with GuitarRox - you need to see your doctor before taking any more antibiotics.
Getting tested will have to wait until 2-3 weeks after you finish the flagyl, which I'm not even sure why you're taking that. Are you thinking trich?
It can take some time for symptoms to fully go away, but you aren't sure your symptoms were even a return of chlamydia. You might have been dehydrated, have a urinary tract infection, or at 44, have a prostate issue.
Please make the time to see your doctor.
You haven't seen a doctor yourself? You took the medication her doctor gave but now are taking flagyl and have taken doxy as well? Who prescribed that? I really do not recommend treating yourself if that is what you are doing. Go to the doctor yourself. Get tested for chlamydia yourself. That's what you need to do at this point.
