Genital Herpes and pregnancy

Any advice? I'm about 7 weeks pregnant and feel an outbreak coming and although I've have other kids I never had breakouts with them...

I havnt gone to the doctor for my first ob apt, and I won't until 2 weeks from. Now. Any advice. On what I can do? I usually take lysine supplements when I feel the tingle along with using tea tree oil to treat and it usually goes always within a day or two but being pregnant is this an option for me?
