Could I be?!

So my period is 3 weeks late (as of Sunday 10/4) and my boobs are sore and swollen, I have gained a few lbs and have been super bloated. I get random cramping here and there like period cramps but they only last about 20seconds then subside... 
I have had a dr appt for this Thursday to have my yearly woman exam and talk about switching my birth control method.. It's been set for a few month now..Will my dr be able to know from my exam if I am pregnant or not.. Without a test yet? Is that something that can be noticed whole feeling around in there during a pap?
