Heartbroken

So my period was suppose to start on Friday, January 22, but nothing happened. I had my usual cramps, but not my usual premenstrual spotting. I felt a little queasy that afternoon and my heart was racing, I was so excited, but knew that I would need to wait out the weekend. Which I did, my cramps were horrible all weekend long. Extremely severe after a terrible fight with my little sister on Saturday night, I was so scared, I thought what if I just caused myself to miscarry. I laid down and relaxed and the cramps eventually subsided. On Sunday everything seemed to be fine. I took a nice nap and then relaxed when I got home from my Mom & Dad's house. Then the spotting began, and I fell apart. I tried to remember that spotting is also normal in pregnancy and it was nothing. This morning when I woke up my boobs no longer hurt and I just didn't feel the same. I went to work and talked to my boss and she insisted I call my Doctor. He was not in, but his nurse told me to come in for a blood test. I would finally know. She called me about 45 minutes later and told me it was negative. My heart sank. I feel so empty. Brian is out of town and I have no one to talk to. I also feel terrible, Brian was so excited and I know his heart is broken now too, I heard it in his voice when I told him my results. I am still waiting for my period to start and I can't stop crying. I want to just stay home and sleep, but I have to go back to work.
