You can typically start to feel your baby move between 16 to 24 weeks of pregnancy. If this is your first pregnancy, you might not feel movements until around 20 weeks or later. For women in their second or subsequent pregnancies, baby movements may be felt earlier, sometimes as early as 13 to 15 weeks. The first movements often feel like gentle fluttering or swirling inside your belly. As the pregnancy progresses, these movements become more distinct, including kicks and jerky movements. If you have not felt your baby move by 24 weeks , it's important to notify your midwife or doctor so they can check your baby's heartbeat and movements. You should feel your baby move regularly up until and during labor. Each baby has a unique movement pattern, so getting to know your baby's usual pattern is helpful. Also, babies tend to be more active at certain times, often in the afternoon or evening. If you notice a decrease or significant change in your baby's usual movements, seek medical advice promptly.
