I'm pregnant!!!
We were shocked at first but I think we have moved past all that to just beyond ecstatic now.  I don't even have words to explain how I feel.  This is truly a miracle that we had been told would most likely never happen for us again, for unexplained reasons.  AMAZING!!
So, on July 4th, after feeling really icky for a week or so I decided to take a test - who knows why, just a random thought.  To my incredible surprise it said positive!  I couldn't believe it.  I yelled for Mark, who came running while wondering what was wrong. I was shaking so hard that he couldn't even see what I was holding so I had to explain it to him.  He was in shock also.  Then he went to the store, upon request, to buy 3 additional tests but different brands, to make sure it wasn't a false positive.  After those 3 were positive also we went to my doctor for a blood test - I still didn't believe this.  As we were driving I kept thinking of all the other possibilities...I could be in renal failure with excessive protein in my urine causing a positive pregnancy test, I could have a uterine or ovarian tumor causing the HCG hormone...it was too much to actually think we could be having a baby.
The next day I got the positive blood result from the doctor - we really are going to have a baby!!  Since then we have had 2 ultrasounds - the first was too early to show much more than a blob, but the second (just yesterday) showed the beautiful heartbeat and gave a due date of March 7th.  
The boys are also pretty excited and can't wait to start shopping for a new sibling.  This is such a miracle!
