My situation

So I was supposed to have ovulated on the 1st or around then. Some people say I didn't ovulate? But my opks said I did. And I had the perfect cm that day. So now I'm about 11dpo and I have a slight mild yeast infection for the first time ever in my life. My af is due on the 17th. I also swear I had implantation cramping. My pregnancy test came back negative today but I know it's also too early to test. What do you think? Could I be pregnant?
