I had sex for the first time 6 days ago. I trust my partner and he's told me he's been checked and he had nothing every time I've asked him. After we had sex I had no weird symptoms. 3 days after we had sex, my period started. On about the 3rd day I experienced itching. No type of pain, no discharge, no burning, just itching. I have a history of on and off bacterial vaginosis and yeast infections for the past 2 years. I just want to be sure if it's another one of those issues again.
