Yeast infection or allergic to condoms? Or something else?

So for the past few days I’ve had some mild itching right around my vagina. It’s not excruciating by any means, I notice it more if I’m wearing lace underwear or certain pants. Last night I noticed discharge that looked somewhat like what you would expect with a yeast infection, but that was the only time, didn’t have anything abnormal today. Nothing smells.

This week my boyfriend and I started using condoms which we haven’t done in probably a year. We haven’t had sex in two days and I’m still feeling itchy so I’m confused. I’m positive I don’t have an STD.

Any thoughts would be helpful! I’m on birth control so next time I will try without the condom and see if that helps but for now since I’m still itchy Im looking for some advice!
