One week til ovulating, could I be pregnant?

I know that it’s very extremely rare to get pregnant before you ovulate. But not impossible. I bd right after my period ended. The next day I just felt completely off. Unusual mood swings (which I usually experience right before my period). Lightheadedness, and the next door tender breasts (which usually I get when ovulating and my period is starting). Do you guys think there’s anyway I could be pregnant. I do know that these symptoms could also be for other things too.
