I am four months pregnant, and go back to the doctor on Feb.6. At my last doctors appointment he told me that I havent gained any weight so far, but my stomach was growing so the baby was gaining all the weight. I was advised to only gain about 20 pounds during my whole pregnancy because with my first pregnany I gained ALOT of weight and I was already a little over weight at the beginning of this pregnancy. I weighed myself at my mothers house and it looks like I have gained 3-5 pounds since January 9. Is this bad considering this is the only weight I have gained so far?!? How to I keep my weight from sky rocketing like it did with my first son?
