for about four weeks ive had about 5-7 bumps show up which look similar to some moles i have had forever on the rest of my body. two are located about 2 inches below my belly button the rest are even lower. i tried popping one to see if it was a pimple but it just turned into a blood blister and now is starting to look like before i tried popping it. i am 25 years old and have been in a relationship for six months. not sure if this could be an std or something else.
