Catching up on my nesting. I missed the second half of your question the other day. ?I'd ask for you doctor's opinion about weight gain, since it is a very individual thing.
At my 30 week appointment I was up 12 pounds from my starting BFP weight. However, I packed on almost 20 pounds in the 3 months leading up to it. I was eating like it was my job in order to get that BFP, so I was at a good point when I finally got it
Most of my weight gain was in the 1st and early 2nd tri. Even though nothing sounded good I was constantly nibbling to keep the nausea away. Since I was at a normal weight by the time I got my BFP, my doctor hasn't been concerned about my weight gain. At my last appointment, she did say she wants to see me gain at least a pound a week for the rest of the pregnancy.
Just make sure you are eating balanced meals and a couple snacks each day.?As long as your getting the proper nutrients, and not restricting yourself, your weight should level out naturally.
