Yes, it is possible to feel the baby at 11 weeks, although it is more common to start feeling movements between 18-25 weeks. At 11 weeks, your baby is still very small and their movements may not be strong enough for you to notice regularly. The sensation you described could be attributed to various factors such as gas or muscle twitches. If you are unsure, consult with your healthcare provider who can provide more accurate information based on your specific situation. As your pregnancy progresses, you will likely experience more distinct and noticeable movements from your baby.
