PLEASE HELP- Super nervous 😥

Okay so I've been realllly itchy down there and it's super red and irritated now. I don't know if that's from the scratching or what. I got off my period on the 29th and had sex on New Years and I've had weird symptoms since then. It was unprotected sex and the guy came in me. I took plan b the next day and then had kind of like end of your period spotting. That stopped the same day but then I started getting it again last Friday the 8th and it hasn't gone away since. It's like a period in that it's been every day but it's not like a period in the sense of like the flow and stuff.  Also, today there was like these white clumps of discharge coming out with the spotting too. And it burned when I peed but it was only after I had showered. Other than what I mentioned as far as the itchiness and redness and spotting type thing I have no other symptoms. Like there's no odor or anything. 
Can someone pleaseeeee help me I'm super nervous and idk what to do 😓😓😓
