It is common for women to start feeling their baby's movements between 18-25 weeks of pregnancy, but every pregnancy is different. If this is your second pregnancy, you may be more attuned to the sensations and recognize them earlier. However, if you haven't felt any movements by 18 weeks, it's always a good idea to consult with your healthcare provider just to ensure everything is progressing as expected. They may recommend an ultrasound or other tests to check on the baby's well-being. Remember that every woman and every pregnancy is unique, so try not to compare yourself too much with others. Trust your instincts and reach out to your healthcare provider for reassurance and guidance.
