Advice ladies? Tmi.

Hello! I'm 16 weeks pregnant, and for a couple of days I have a swollen and sore and itchy down there area.

I've brushed it off as a common pregnancy symptom but due to go doctors on Monday as it's getting so painful.

It's more of a red/blues colour my clit and lip on the left side gets it worse my clit is very itchy and white stuff appears around it.

I may understand I sound very stupid but with this being my first pregnancy and this is very uncomfortable for me I just want to know if any ladies have or had this when they was pregnant I cannot sit down or walk I cry in pain as I felt nothing like it. Can I put anything down there like rub ice cube on it gently ? Or anything? Thank you :)
