Pregnancy pain?

So I ovulated Saturday the sixth, with my normal ovulation pains. Well, earlier today, I was nauseous and bloated. No REAL vomiting (twice I did just a bit in my mouth but I don't think that's the same thing as actually vomiting). Took a nap for an hour and nausea was gone. I just had a sharp pain towards the left side of my uterus (the side I ovulated on). It lasted about 3 minutes and then faded. Since I'm only about 5 DPO, that's too early for this to be from implantation/pregnancy, right?
