I work at a spa where I was preparing the electrolysis tweezers for sanitation in the autoclave. I was wearing gloves but one slipped and stabbed me through the glove (enough for it to bleed a bit). I took the glove off and cleaned it immediately after, but I am 7 months pregnant and worried about contracting something that could harm my baby (such as an STD). I know I can get tested but also heard that certain STD's don't show up on a blood test for months. Should I be worried?
