How long after unprotected sex should i get std testing? i used a condom, but it broke so i just want to make sure i'm safe.

2-3 weeks and 3 mos.: There are many possible sexually transmitted infections, including syphilis, hiv, hepatitis, gonorrhea, chlamydia, herpes, trichomonas, and human papilloma virus (hpv). Some of these have helpful tests to check for them, others do not. How long these tests take to turn positive varies, with some taking as long as 3 months. It is ok to check after 2-3 weeks, but i would check again after 3 months.
