freaking out a bit

I'm 11 weeks 4 days. My partner carries hsv 2 but has never had an outbreak. We have both been on suppressive dose of meds since starting to try to get pregnant. Yesterday he noticed a bump and today it definitely appears to be a minor outbreak. I'm worried because I know a primary outbreak for me now would be dangerous for the fetus. I'm freaking out right now. Aside from calling my ob immediately tomorrow... what do I do?! **we had unprotected sex a day before he first noticed the area getting itchy
