You could have, but are you sure it's an ob? Or only an ob? Could you be having a ghsv1 ob and hemorrhoids? Or have a secondary infection like another STD?
Does your partner have hsv2?
The only way you'll know is to get it cultured. Depending on how long it's been, it may be tricky to culture. Ask for a PCR swab - it's way more sensitive.
Your partner could take a type specific IgG blood test to find out if they have hsv2.
Let me know what you find out, but get checked as soon as possible. Feel better!
