Since I found out I was pregnant I changed my eating from dieting to maintenance mode. I have been doing a lousy job at it where I don't eat all my calories (1,900), I usually end up eating 1,500 at the end of the day. I was doing a low Carb diet before so I had to up my carbs from 20 to now 65-70 carbs a day. But even those haven't been met, I sometimes will barely hit 60 but mostly its 50-55. I also started exercising to help me maintain.
Well since I found out I was pregnant, I've now gained 6 lbs. I haven't really been going #2, when I do it doesn't seen nearly enough so I know its just getting backed up. I've always had a problem with constipation. A couple months ago I started taking an herb to help make me more regular, since finding out I was pregnant I stopped taking it.
Here's what I normally eat in a day, I'm used to routine so this is pretty much it and I don't really get bored eating it. Unless we decided to go out and even then, its only one cheat meal for that day but this doesn't happen too often and I still make sure its not a major cheat:
breakfast:
2 eggs, 2 bacon, a slice of toast w/butter, a serving of cheddar cheese. And hot tea w/ cream and sugar
Lunch: poached Tilapia, steamed cabbage (3 cups) w/ butter, and sometimes another serving of cheddar cheese. Drink:water. Sometimes I trade the cabbage for a salad (3 cups of lettuce, 1/4 bell pepper, and 3 tbs. ranch dressing).
Dinner: Chicken breast, salad (3 cups lettuce, 1/4 bell pepper, 3 tbs ranch dressing). drink: water or hot tea
snack: will either be 1/4 cup of mixed nuts or 1/4 cup of dried fruit. Or 1/4 cup sunflower seeds.
I measure and keep track of everything I eat, so I make sure any snack I have is okay so that I don't mess up.
am I not eating enough veggies? I do take my prenatal vitamin, Omega-3, and Super B-Complex vitamin.
I look bloated. :-(
I know this is my #5, but this is also the first time I'm trying hard not to gain weight like I did with my others. Other times I would already be going hog wild saying "Oh well, now I'm eating for two." Yeah whatever, those days are gone, I want to only gain what I need to but my body doesn't want to cooperate. :-(

And if that fails, try some ground flaxseed (great with the Omega3's and fiber) to sprinkle on some oatmeal, cereal, yogurt, etc. I actually just take my 2tbsp of it with water daily if I don't eat any of those in my meals.
