These are not symptoms of any std including herpes. New infection symptoms for herpes would be genital blister type sores that appear about a week after followed by flu like symptoms. What your describing maybe anxiety related but surely not herpes.
What type of symptoms as 4 weeks is a bit out side the window period and oral is really low risk and if she did not have any open lip sores at the time the risk is close to zero anyway. You can amost certainly rule out hsv2 as her having this oral is extremely rare.
Hi whats seems to be your issue?
