Having passed my first trimester, it seems like it will only be a matter of time before my weight heads north. To keep track of my progress and make sure I don't put on more than I should, I've found a useful chart from an informative website:
Pregnancy weight gain metric chart
Your pre-pregnancy weight ( Kilos )
| Your pre-pregnancy weight ( Kilos ) | ||||
| height | underweight | normal | overweight | obese |
| 1.52 | <> | 46 - 60 | 60 - 66.5 | > 67 |
| 1.57 | <> | 48.5 - 63.5 | 63.8 - 71 | > 72 |
| 1.63 | <> | 52.5 - 68.8 | 69 - 77 | > 77.5 |

Where do the pregnancy Kilos go?
Maternal stores of nutrients
and muscle development 3 Kg
Increased body fluid 2 Kg
Increased blood 1.5 - 2 Kg
Breast growth 600g
Enlarged uterus 1 Kg
Amniotic fluid 1 Kg
Placenta 600g
Baby 3.4 - 4 Kg
Total 11 - 16 Kg
On a Trimester Basis:
* First trimester: Most women put on around 1.8kg in the first three months.
* Second trimester: around 0.5kg a week for the next three months (5.5 - 6.4kg) in total.
* Third trimester: and only around 4.6kg over the last three months.
But remember, these are average figures for large numbers of women so just because your weight gain pattern is different, it doesn't mean anything is wrong.
