Herpes during pregnancy
The severity of your symptoms may vary depending on whether you have had attacks before and how far into your pregnancy you are.
If you have already experienced a genital herpes attack before you got pregnant, you will have developed antibodies to the herpes virus. Therefore, the risk to your unborn baby is very low as these antibodies will protect your baby from the virus.
If you have your first attack of herpes during the first trimester of pregnancy (the first three months) then this carries a small risk that you will miscarry. There is also an increased risk that you will pass the virus on to the foetus.
If you contract genital herpes at a later stage of pregnancy, the risk of passing the virus on to your unborn baby is higher. The risk is particularly high if you have a herpes attack around six weeks or less before you are due to give birth.
