Could i be pregnant

Lily
I had un protected intercourse a coupld weeks ago and monday i went to the gynecologists for the first time. So they made me do a pee test (which i thought was also a pregnancy test) and i got checked out and such. They never called back for results and my mom who goes to the same place said they usually don't call back unless its a positive . Now today i was supposed to get my period and i have been having cramps all day. Its only 3 and when i went to the bathroom there was no blood yet i smelled it.... 
Could this mean anything? Or should i wait.
