It is not uncommon for women carrying twins to feel fetal movements later than those carrying a single baby. At 15 weeks, it is still early in the pregnancy, especially considering you are carrying two babies. Typically, first-time mothers may start feeling movements between 18-25 weeks of pregnancy.
The position of the placenta can also affect when you will feel the movements. If the placenta is positioned towards the front of your uterus (anterior placenta), it can act as a cushion and make it more difficult to perceive fetal movements.
However, if you are concerned about the lack of movement or if you notice any other unusual symptoms such as severe pain or bleeding, it is always best to consult your healthcare provider. They can perform an ultrasound or listen to the babies' heartbeats using a Doppler device to ensure everything is progressing well.
In the meantime, try not to worry too much as every pregnancy is unique. As your babies grow larger and stronger, their movements will become more noticeable over time. Remember to take care of yourself by eating a balanced diet, staying hydrated, getting enough rest, and attending regular prenatal check-ups.
If you have any concerns or questions about your pregnancy journey, don't hesitate to reach out to your healthcare provider for guidance and reassurance.
