Yeast infection or pregnant?

Today is a day or two after I supposedly ovulated, and I had a lot of white discharge today. I realized it was kind of clumpy?? I'm worrying that it's the kind of discharge you get right after an egg is fertilized...

the last time I had sex was last week and I used a condom. I know condoms aren't 100% effective, so that's why I'm worrying. Please help.
