Confused NEED ADVICE?!?

Still a little confused about my last period.

My cycle is 5-6 days long every 30-32 days

And ovulation ends 2weeks before my period. We had intercourse 2times during fertility week. Period was two days late which is normal but my period only lasted 4 days. My boob's are a little tender and Ive had nausea spells every now and then. Can sleep 12 hours and not wanna get up. I really wanna have a baby we've been together 4years and trying for 3 of them. Is it possible I'm pregnant or is it just my mind playing tricks on me because I want it so bad???!!
