I got tested 4 weeks after a pimple on the very base of my penis and it was negative...i also just did a test at 12 weeks which was .94 and .91 was negative and 1.08 was positive so it was inconclusive...what do you think...both were igm tests and im sure that by 12 the pimple i was worried about would have shown up...my doc just says move on and dont get tested anymore its driving you crazy ...thanks
