Is it possible for me to be pregnant?

I just finished my period Wednesday the 24th. This time my period was weird. Usually I'll have like one day where I stop bleeding for most of the day, but this time my period came for 2 or 3 days then after that it was only a little not even enough to say so. For the past 4 days I have been very nauseous, some smells and tastes make me even more nauseous. I've also been dry heaving or gaging. My soon to be brother in law and sister in law think I am. I've been ttc for 8 months now. What do you guys think?
