So I had unprotected sex 2 almost  weeks ago when I was ovulating  , I get headaches at times for no reason & feeling dizzy , also last night when I was about to shower my nipples were feeling sore .  Also when I see food i really  like I honestly don't feel like eating it idk why . Can that be a pregnancy symptom or ? I'm supposed to get my period next Tuesday .  My boyfriend keeps saying to take a pregnancy test but I feel it's to early & also I don't want to get my hopes up .
