So for the past few weeks my vagina randomly itches and/or burns.. sometimes it’s only during or after sex with my boyfriend, other times it just happens on it’s own. Sometimes it burns while I pee but hardly ever. I have no discharge and no funky odor... any ideas on wtf it could be?

At first I thought it was my hormones, I had a baby 7 months ago and I’m breastfeeding, I just started having my period when he was 6 months old. My cycle is pretty off because of the hormones.
