I would know if I had a yeast infection right ??

I know it sounds stupid. But I've never had a yeast infection before in my life. Of course me and my husband are ttc. I've noticed some irritation lately every once in a while in my vaginal area. I started to wonder if it's just due to so much intercourse. Or a yeast infection. I've never had one so i have no idea what they feel like. But I was told if I had 9ne I'd know it. Any suggestions appreciated
