I’m 2 weeks late.. no symptoms.. could I be pregnant?

Olivia M Asked: I’m 2 weeks late.. no symptoms.. could I be pregnant?

I am 21 years old, and my last period was June 15, 2011. It is now July 2, 20011, and I still don't have my period. Usually when I am close to my time of the month, my breasts swell, and often get tender, and I feel crampy and get bloated. But not this time. My breasts feel and look the same, but I am more lathargic than ever, and often can't sleep, and wake up a lot in the middle of the night feeling hot and bothered. I feel full of anxiety at times, but have a lack of energy. The only thing that is normal, is that I am starting to break out a little around my mouth and chin with some acne. But other than that, I feel pretty much the same, just 2 weeks late. My boyfriend and I don't have the safest sex… we only use the "pull out" method. I know I deserve a slap for that one for sure, but the only good thing is that we are the only partners that we each have. We pretty much live together and see eachother every day. I know that we are careful. But if anyone has a comment .. please help.Thank you…

p.s. I also took a HPT a week ago and it was negative, but I'm about to spend another $20 to buy 2 more… I'm freaking out.
