Ladies help

Ladies im 13 weeks pregnant! Went for my first ob appointment in January! Recently went back and doc told me i had a sign of Herpes in my blood stream ! Keep in mind im always up to date with my testing , so that was a huge shock to me ! My ex boyfriend and i was tested in January before the appointment and all std testing was NEGATIVE ive never had another partner in all 8 years of me and him together! He hasn’t either! Never had any signs of the virus doc didn’t even tell me a type!! Should i get RETESTED or believe the dr ? Im so depressed about this
