During the first trimester of pregnancy, you will experience many changes, including increased fatigue. Here’s a list of other changes you might expect:

  • Breast sensitivity
  • Swelling
  • Tiredness
  • Emotional changes, like mood swings, sadness or weepiness, thanks to changing hormone levels
  • Increased/frequent urination
  • A dislike of certain foods and food smells
  • Upset stomach/nausea/vomiting
  • Vaginal discharge/spotting
  • Abdominal cramping and pain in the lower back or buttocks
  • High temperature
  • Thickening waist

Throughout your pregnancy, you should gain anywhere from 25 to 35 pounds, but much of this weight is gained in the second and third trimester. Fluid retention may play a part in early weight gain.
