I recently learned I have herpes simplex 2. Apparently I ve had it a while, but I recently switched doctors, and my new doctor tests asymptomatic people for herpes. Anyway, I started Valtrex immediately to reduce the risk to my partner, but I ve had minor breakthrough bleeding the whole time since I started the medication. It s really bothering me, and my confidence has already taken a huge blow from the diagnosis. Is there anything I can do about the bleeding? I have a Mirena IUD as my primary birth control method and I use condoms.
