Actually I would assume the woman would have been tested when she went to the OBGYN (is that the right doc? Whatever, girl stuff)<quoted text>
I think sometimes you are looking so hard to defend the man you don't look what's in front of you.
But there was no mention of her telling the guys she slept with to get checked if she came back positive.
It could be that Abby knows the miltary tests for STDs -- that I don't know.
