Am I Pregnant?

We've really been tryin for about a year. I started a new job 3 months ago, and since, my period has been playing tricks on me. 3 days late, 5 days late, 2 days late. Stress I told myself. But every time my period came, I'd sit on the toilet, crying.

I think I'm pretty in tune with my body. My husband and I just moved, but he hasn't started his new job yet. He's home on weekends though.

Well, this weekend was the weekend I was supposed to ovulate, didn't even realize it. So, we ended up havin sex, as normal, but then on Sunday I was so tired, had a headache, but didn't feel sick. Just not 100%. Then on Monday, I was just exhausted. So much work to do, so much to focus on, but just pure exhaustion. Then I started feeling a little crampy.  Weird, too late for mittelschmerts (however you spell that), and then I started feeling nauseous as I went to bed. Cramps continued on Tuesday, and I was super bloated. Today, less bloated, cramps continuing. Yet, urine home tests are negative. I feel a weird pressure down there, no cramping right now, but a pressure that isn't usually there.

I just want to be pregnant so bad. Is it just my imagination, or could it be possible?
