what does this look like?

Recently I been itchy down there but I don't have discharge that stinks at all... have milk like discharge with little white chuncks at times... I'm googling things and it comes up as a yeast infection... so I wanted to know if anyone has experienced this? I know I don't have an std just had a pap down three weeks ago and haven't had intercourse since before that... any thoughts? I do plan on calling my doctor to go in on Monday but it's just so itchy right now and would like to know what I can do for the meantime or put for the meantime. Also I'm pregnant 23 weeks... so anything that I can use while pregnant would help.
