Herpes Doctor

My parents have been away for a couple of days now, so my boyfriend have been active during this time. He Knows i have herpes so we've been using protection ike we always do. Anways woke this morning and the area after my perinium ( don't kno if i spelt it right) was hurting. I felt it and there was a little lump there, it makes it verry painful to sit and walk so i just wanted to kno if i'm having an outbreak because i've never showed any signs of havin herpes. I still don't quite understand how i got it since i've never had sex without a condom. My Doctor told my that i've b'come immune to it but the info i've read doesn't say anything about immunity it just says the virus lays dormant until the opprotune time. I have a really bad cold as well, plus my haemoglobin is low (not low enough to be anaemic though) so i just really need to kno if my swollen lymph gland is a sign that my herpes is 'flaring up'. This is not the first time they have been swollen. Oh and one other thing i have signs of a yeast infection too. So i'm really trying to figure out what is going on with my vagina because its really bothering me
