Irritated Vagina

Okay so my SO and I had sex the other day. I had barely any hair down there but it was sorta "prickly" 🙈 anyways we had sex and me being pregnant sex is great but sometimes uncomfortable. I had trouble staying wet at one point so I think him rubbing against me irritated my skin. After we were done I showered and went to bed. Ever since then my vagina has been itchy, irritated, and swollen.. I'm not sure if it's a yeast infection but it's driving me insane. I've never had this problem before. Has anyone experienced something similar?
