HELP confused

Ok so today makes two weeks since I was supposed to start my period. I have never missed one before. I have only pooped twice in two weeks, my lips are super dry and chapped, I been sleeping alot more and have had mild cramps. I took a couple of tests but they were negative. Im planning on calling the doc tomorrow to schedule a blood test. Im just wondering if anyone thinks I may be pregnant by what I have just said?
