Could I be pregnant?

So I had unprotected sex on the Fourth of July. And recently I went through my fertile week. Anyways I been discharging so much that it feels as I wet myself when I wake up. ( which I'm not used to at all) I've been dizzy as well. I'm very worried and I was wondering if someone can give me any advice. Is it to early to be feeling like this? Or am I just overthinking.
