NO sign of a period

So, this is my first time posting something like this.Here I go... my husband and I haven't really been "ttc", it's more like a "whatever happens, happens" type of deal (for lack of disappointment). But i would be EXTREMELY HAPPY if I am preggers. Anyways... The first day of my last period, was MAY 14,2011. My average cycle is 45 days, which means my last one should have started JUNE 28th. Well, needless to say... here I am on JULY 16th, and still NO sign of a period. Not even spotting!!(which is normal for me before my period.) I haven't really had too many of the "most common" early pregnancy symptoms. But, for the last 2WEEKS I have this queasy feeling that just wont go away!! Sometimes I do throw up, but its rare. Also, I have been feeling A LOT more sluggish and fatigued lately. Certain foods are starting to give me heartburn and indigestion. I feel bloated ALL the time. And don't even get me started on how many "pee-breaks" I have to take a day. I know you guys are probably wondering why I haven't taken a test yet. But the truth is, I'm terrified of the disappointment. I know i just need to put my big girl pants on (lol), and just go get a test. But for some reason, its easier said than done...
