Question for those who have used MFP during pregnancy

I was allowed to lose weight through my pregnancies, but that's because I'm morbidly obese. However, with that said, I was closely monitored by the dr, and was told to add about 200 cals (daily) to my diet - and they had my previous calorie count- however, my diet was modified, because I had to add extra protein and calcium to it, and there wasn't enough in the 200 cals to accomplish that - so had to give up some of my "snacks" that I had - you know the 100 cal packs of snacks that really don't offer a lot of nutritional value, but just for the sake of having a snack that's yummy - so it was def a modification to my diet plan. same thing after my sons were born, while I was nursing them, I could have the extra 200 cals added in.
also, some of the things that help with morning sickness- the B-natal lozenges/pops - I would order them at Walgreen's and they helped, and also ginger helps with it, so sometimes a ginger snap could help, but my go to was smoothies- and not early in the morning, just about 2 hrs in, and I could have one.. hope this helps! my boys are now 3 and 1 - so ask away!

I didn't use MFP during my last pregnancy, but I acknowledged after my miserable second pregnancy with 55 pounds gained that I could not go through that again. I didn't count calories, just ensured that I ate lots of fruits and veggies, made sure I brought lunch to work so I wouldn't succomb to eating chocolate bars and cookies and cake as a meal, and only had ONE serving of dessert. I gained 30 pounds with my third baby and felt 10000000% better! I also went to the gym 2-3 times per week to do some low-impact cardio, usually for 20-30 minutes. And when that started to feel like too much (about 8 months along), I cut out the gym all together.

I now weigh less than I did after my second child was born (baby is now nine months old), and I don't think I've been this small for about three years. Still about 20 pounds to go to get to my pre-firstborn weight, but only about two pants sizes. Holla! LOL

For me, too, I had no idea how many calories were in things, never had a problem with weight until I got pregnant and just packed in on like there was a famine coming. And I think breastfeeding helps a lot, too. Not only does it burn off a lot of calories, but I'm still period-free (if that's TMI, sorry) so I don't get all the crazy hormonal eating binges. I think that's been a huge help to me.

Anyway, bless you in your journey, and probably just being aware of the impact your food choices have on your weight makes the biggest difference in a moderate weight-gain pregnancy and a grossly-out-of-whack weight-gain pregnancy. IMHO

Edit: I do use MFP to track my 500 calories for breastfeeding, too, since I'm not about to starve my little one trying to get the last pounds off. (She's a beautiful butterball, though! The thighs on that one--amazing!)
