I tried these last weekend and now I'm addicted...love them! That's probably why I got in trouble yesterday from my doctor - I've already gained 11 pounds, which is 3 too much! Oops, I thought I was doing better the last couple of weeks. I had a heavy sweater/jacket thing on yesterday and um, maybe the baby is just getting big fast??? haha. She estimates I'm between 15-17 weeks but after I get another sonogram in 3 weeks, we will know better. Until then better lay off the Cheez its.
