Could this mean I'm pregnant?

Iv been having a little bit of symptoms including soar breasts and cramping. AF is due tomorrow. I had a pos ovulation yest on the 28th just like glow said I would. I heard that you can use an ovulation test as a pregnancy test, that it detects the same hormones. So I just had an extra one and decided to take it. (For fun I guess) This pos looks darker in real life but I have never had a dark like this close to af. Do u think I could be pregnant?
