Incomplete pregnancy
If the baby has not grown up, the abdomen will naturally not bulge. Usually, after 16-20 weeks of pregnancy, the stomach will gradually emerge.
Abdominal muscle tension
Athletes and fitness enthusiasts, please note that your abdominal muscles may be too tense, which affects your abdominal bulge.

Abnormal uterine position
In women with a lower uterus or uterus, the abdomen may not be obvious. However, the safety of the baby is the most important.

Mothers with twins or multiple births have different degrees of tummy, but every baby is worth looking forward to.
