We were originally waiting so our son would be a bit older (closer to school age) before we had another one.
Then in May 2012 I got a year-long contract at work, with options to extend after the year. I wanted to be close to that year before getting pregnant so they wouldn't have any reason not to extend it. Now, due to financial circumstances in the company, the job no longer exists, and as of January I will be returning to my previous position.
Also, a few years ago I severely broke my leg, which resulted in emergency surgery. Now, almost 3 years later, I need to have surgery again to remove some of the hardware they put in my leg in order for it to heal. My surgery date is January 7, so that's the day we'll be TTCing, probably immediately following my release from the hospital! lol We've really wanted to TTC the last couple of months, but my leg hurts so much that I just can't put off the surgery for another 9 months to a year.
