Red bump

I had sex 3 days ago with a new partner , without a condom. I have had 2 other sexual partners over a course of 2 years and got tested everytime. Nothing is bothering me but I decided to look at mt vagina to make sure everything seemed okay. I noticed this bump , not itchy not other symptoms . What could it be ? What does it look like?
