Why Is My Pregnant Belly Bigger at Night?

During the first weeks and months of pregnancy it’s exciting to watch your belly grow. However, as your pregnancy progresses, you may notice that your belly can change in shape and size in as little as a few hours. Particularly at night time, you may notice that your belly looks bigger, then is smaller again in the morning.

 

Why Is Your Belly Bigger At Night?

At night time, your abdominal muscles are more tired from the strain of holding your bulging bump. The muscles loosen as they grow more tired, which allows your bump to sit out further and appear larger.

When you go to sleep, your muscles get a chance to rest and recuperate so they’re refreshed and ready to maintain your bump’s position when you wake.

 

What Are Some Other Reasons Your Belly May Be Bigger, Smaller or a Different Shape?

There are a range of reasons that your belly can change in size or shape. The most important thing to remember is that your belly doesn’t show how big your baby is. You can have a large baby and a small bump, or a small baby and a large bump. Genetics, how you carry your weight, where the baby sits and other factors all impact on the size of your bump.

Some reasons your belly may change in size or shape:

• Baby has engaged in the birth canal. This can happen as early as mid pregnancy or as late as mid labor. Once engaged, your belly can be smaller.
• Baby has changed positions. If baby turns breech, posterior or transverse, your belly may become larger due to their position.
• Baby may be sitting on one side of the uterus, which can make your bump uneven or bulge on one side.
• Water retention, bloating or a big meal.
