Help..?

Okay so I have an appointment tomorrow. Just wanted to see if I was the only one...I’m in my 5th week of pregnancy. My vagina feels irritated as F**K. Tried having sex this morning and it hurt so bad I was in tears. Felt like burning and like my vagina was swelling shut. I have normal creamy discharge. No odor. Could it be yeast infection or what’s everyone’s thoughts??
