I ve only had unprotected sex with 2 people, when me and my boyfriend would sometimes if he didn t shower before my pH balance would be knocked off and my discharge would have a fishy smell, but when I got my period the smell would go away. I recently had unprotected sex again with another person and I had a fishy smell and even after I got my period the smell would still be there. If I have a std it will ruin my life, is this a sign I have one?
