I'm 34 weeks with my first and I decided that I'm going to try them. They sell the disposable pads at my local grocery store and I ordered the little pants and liners online. I really hope they work and aren't too messy!
I flew from New York to Denver and back again when I was 8 weeks. I'm now 32 weeks and doing great. Just make sure you get up every hour or so and move your legs around and stay hydrated with water. You'll be fine.
Congrats Jen on your healthy baby girl!!
Check out my photos, I used the digi FRER to get my BFP.
