well that is what happened to me. as i said, i didnt even kno i had it until i was 7 months pregnant. my ob had me take valtrex during my last month and checked me when i was in labor. my hasband also has elected to take the risk and go without condoms. we've had an active sex life for 8 years and he's never contracted it, and he doesn't want me to take the medication although i would be happy to.
