First Trimester
Dr. Stephen Strange
The first trimester of pregnancy is marked by an invisible — yet amazing — transformation. And it happens quickly. Knowing what physical and emotional changes to expect during the first trimester can help you face the months ahead with confidence 1.
Some of the physical changes that occur during the first trimester include tender, swollen breasts, nausea with or without vomiting, increased urination, fatigue, food cravings and aversions, heartburn and constipation 1.
