another ultrasound scheduled!

We have another ultrasound scheduled for April 21st. Since the tests results came back normal last time they don't think it's necessary to re-test, but we insisted. We are dying to know the sex and want to make sure everything is OK at week 22 since the last test was a little early and gave us a scare. ;o)-
I heard the heartbeat at my appointment on Thursday.
I've gained 12 lbs so far, but everyone says they can't see a tummy yet.
I've been feeling a little better the past couple weeks, but still get the headaches. Thank goodness the nauseousness is finally gone. I'm trying to continue my daily work-outs but at a lower intensity. I'm officially out on disability from flying as of March 25th.
