i previously got syphilis from a boyfriend. i took medicine to get rid of it, and when he went to get tested he tested negative. i recently engaged in sexual activity with him again, and my body is recently acting weird. i have a bump in my lower abdomen close to my pubic area. it hurts when i press on it. im releasing a lot of discharge its white. and i cant hold my urine for very long. Should i be worried, or is it something other then an std?is it possible that he tested negative although he had it.?
