By week 12, your baby has gained up to a whole 0.5 ounce! They are plumping up, and they are about two and a half inches long. By this point, their vital organs have developed (which is why it is so vital to avoid doing things like taking drugs, drinking alcohol, smoking, etc.) Doing these things can hinder the baby’s development and cause issues later on. The baby, though fully developed physically, is still maturing; their body is producing white blood cells. Even though they are tiny babies, their pituitary gland is active, and the hormones that will later aid in reproduction, are producing now, in-utero.
By now, your belly is protruding, and the need for maternity clothes has arrived. You are almost to the glory days of the second trimester. One more week, so hang in there. The pregnancy symptoms may or may not be strong. One symptom that may be plaguing you now is dizziness. This comes from the pregnancy hormones and the fact that your blood flow is more focused on getting to the baby. Be sure to keep this fact in mind when you get up, give your body time to adjust, and take things slow. You can keep the dizziness at bay by simply being aware you may have it and act accordingly.
It is the hope that by now you have developed some good nutrition habits. Habits that will help you get more fiber to keep the constipation at bay, habits to eat healthy foods to support the baby’s developing body. Even though the second trimester marks a time when you may feel better, it is still important to continue with good habits. By the third trimester, you will have digestive issues, from a big baby, heartburn, and constipation still. By maintaining good habits throughout you will help to have a better third trimester later.
