I’m on the pill, I have had sex about three weeks ago, with a condom on, the one side of my labia minora is swollen and it is itching, it is hard to the touch and when I touch it, it burns, I have had no weird discharge since I’ve had sex and the smell is quite normal, does anybody have any idea what this could be?!?

I’m also in lockdown so it is very difficult to get to a doctor
