My cycle ended about 2 weeks ago. Could this be morning sickness?

We've been TTC for just a few weeks now, never been preggo, so I don't know what is "normal" for me, but MAN! I woke up this morning and was nauseous, puked, felt fine, then, felt nauseous, dry heaved, and I'm now just feeling a little unsettled, but no real "aches/pains" like with the flu. In fact, I've been cleaning the house like a maniac because I think my house stinks! I'm definitely sensitive to smells this morning....anyway, I COULD just have a bug...but COULD i be preggo? Is this way too soon for morning sickness? Thanks.
