I kept weight each pregnancy and gain less each time. I have six kids and my youngest is 3 months I gained 9 lbs he was 3 weeks early and weighed 7lbs 8oz a nice size and was healthy. It is always important to eat right and during pregnancy you only need about 300- 500 extra calories a day to grow a strong healthy baby. With that in mind if you working being a more fit person you are on the right track. So while you may not lose any weight during a pregnancy you also may only gain a little bit or none at all. Good luck!
