I agree with GBMM...don't worry about it. Honestly, the worrying is worse for your pregnancy than the eating.
I was 5 pounds from my goal when I got pregnant, and I spent the first half of my pregnancy worrying. Then I realized that I was pregnant, and it seemed the more I worried, the more I was gaining. I did have a HUGE craving for popsicles, but stuck to sugar free ones. I'd say I went through a box at least every 2 days.
But all-in-all I was still eating right, yet gaining like crazy. In the end, I put on 62 pounds total. Yet within one week of delivery, I shed 30 of it doing nothing. I still haven't gotten back to where I was, but I'm close, and I'm not putting much effort into it. I do for a bit, drop a few, then just maintain and so-on.
Anyway, I realized during pregnancy that the stress wasn't helping me. So I focused on continuing to eat lean meats, fruits and veggies. But I still felt like I was always starving. And if I was...I ate. I stopped trying to adhere to any calorie limits or monitor what I was eating. I just kept healthy foods around and ate whenever I felt the desire to eat. I couldn't spend 9 months totally obsessed about how much I was eating. And the baby didn't seem to mind the amount I ate. He came out at 9.5 pounds and 21 3/4 inches. LOL
