The third trimester of pregnancy is termed as months 7 through 10 and weeks 26-40. It is really important to continue to make smart choices for your baby including having good nutrition. Too many women focus on weight gain and feel they’ve put on too much by the time they reach this trimester so they scale back. THIS IS NOT THE TIME FOR A DIET! Your baby’s brain grows the most rapidly around month 8 and it needs all it’s nutrients for healthy growth.
What your body is doing
