The first day of my last period was June 8th and lasted for 5 days. My cycles are regular of being 27 days. I was supposed to get my period on July 5th. So far I've been experiencing nausea, breast soreness, strange cravings for hard candy (Which I dont usually eat), fatigue, and missed period.... Could I be pregnant?

sometimes your mind tricks you into having symptoms. If u think your preg your mind tells your body and hence forth nausea, breat pain ect.

it is possible, did you have sex during the time you would of been ovulating? and try taking a pregnancy test.

good luck, hope you get the result you want
