A blood test will tell you if you have it. Also herpes is passed on by skin to skin, not by intercourse or bodily fluids. So even with a condom you can still get it, because his pubic area is touching your pubic area. But the chances are very very slim.
Also I do not take daily drugs because of the side effects. I dryed up like a desert even when I was aroused. So I just deal with the outbreaks as they come. I take acyclovir when I feel one coming. Outbreaks happen when your immune system is down, like when you are sick or under a lot of stress. I have a lot of health issues so I get an outbreak at least once a month. But its my choice not to be on medication. I am sure the meds would help lesson my outbreaks. Some people have their first one and never have anymore, while others only have a couple a year.
Also pregnancy is not as dangerous as it seems. Yes your baby can become infected and there are serious problems. Like still birth, deafness and retardation. this scared the crap out of me. But trust me I have done so much research and as long as you do not have an outbreak during vaginal birth your baby WILL NOT GET IT. Your baby cannot get it through your blood either.
The doctor will test your vagina/birth canal for evidence of an outbreak. If there is none then you can have a normal birth and a completely healthy baby. if there is evidence of an active outbreak then you HAVE TO HAVE a c section. If a doctor tells you you have to have a c section then they are wrong. Also they usually start you on hepes medication right before labor, just to be careful.
I hope this clarifies some stuff for you. Herpes isnt such a bad thing.
