  • Bloated:  It happens because of your uterus takes more space in the pelvic area and you tend to be constipated easily. The changes in predominant hormones slow digestion and on top of all that you gain weight.
  • Constipation or indigestion: Increased progesterone levels cause smooth muscles to relax. That includes your intestines and digestive tract. This relaxation increases the time it takes to digest your food and gives the baby more opportunity to absorb the much-needed nutrition. The fetus also takes water from the mother, causing mom to have dry stools. It takes longer to expel the stool and increases the gas and bloating in the process.

Some women describe the sensation as painful, or as an extreme version of how their breasts feel right before their period.
  • No appetite, Food aversions or an enhanced sense of smell: Some foods are appealing while others may make you feel sick, is all related to hormonal changes in your body once again.
