These are my symptoms, I hate the am I pregnant questions but this is one of them. Still too early to test...?

I feel like I can't breathe all the way in completely, for instance when I sing I can't seem to hold notes as long as normal before needing air. My belly is extended some and when I try to hold it in I'm uncomfortable. I have a moderate about of gas. I normally have diarrhea (my gallbladder was removed 10 years ago and this is a normal symptom.) and now my stools are formed and fell kind-of constipated. I had hiccups earlier before I even ate or drank anything. My are sore to the touch but not painful just enough to wear I notice some tenderness. My husband and I are trying for a baby and I was scheduled to ovulate 7-11-09 we had unprotected on the 9th and 11th. It says if I were to become pregnant during this cycle my due date would be 4-2-10 and that would make me 3 weeks 2 days and it's too soon to test. I'm having surgery 8-11-09 and it is possible they may have to do a full hysterectomy, this is why it is imperative I get pregnant first so they will need to wait. Please tell me if any of my symptoms sound like pregnancy symptoms. I am very anxious and this is my last chance. Thanks everyone and please don't be mean.
