Am I crazy

Emily • Pregnant with #3! Due May 6th 2015
I know the chance of me being pregnant this month is about 1% (bc I have the paragard iud) BUT I have noticed two things that are very distinct that I never have. 
1 is I'm nauseous nearly all day long and 2 that I'm having food aversions even when I'm not feeling nauseous... Like things I love I don't want at all! 
​I'm on CD 28 of an avg 28 day cycle and started cramping yesterday. 
​Last night I woke up with this awful bloated/full and heavy dull pain in my pelvic area accompanied by nausea... Am I thinking so far into this that I'm making myself have symptoms?
