very itchy down there 👇🏼🙈

So it's been going on for a few days. It's been a while since my bf and I had sex, but our sex is always with a condom, so I don't think it's any form of sti. There is no odor and there's no burning when I go to the bathroom. All there is is some clear discharge and it's very itchy. I've been battling a sinus infection for two weeks and I'm on all different meds and antibiotics. I read that antibiotics can cause yeast infections. I've never really had a problem like this before so I'm kinda freaking out. Should I go see a doctor?
