Hi doc. I was wondering if I could catch an std from sharing pants with my twin sister. She wore my pants during thanksgiving this year, and I don't believe that she had underwear on. If she had an std, and than I wore the pants a couple days later, could I catch anything from her? I have noticed in the past couple of days that I have had frequent urination. I went and bought a home test, and it came up negative for a uti
. Could this mean that I could possibly have an std like chlamydia? I recently about 6 months ago was tested for all std's and they came up all negative. Thanks for your advise.
