I'm testing... anyone else?

A
Maybe I shouldn't test, I've got 7 days before my period is due.
(TMI)
But I'm feeling so weird... I've never felt like this... my breasts are... tingling and sometimes hurting it's so weird, cramps.... consistent nausea.  CM is like white lotion....
I just feel super weird.... and every morning i wake up and think: it's in my head I'm not nauseous.  Than I move and I'm still nauseous.
I'm actually afraid of being sick... am I sick?
Can this be some ovarian issue?
