With my first, I didn't feel any form of movement until just after 20 weeks. My placenta was positioned at the front so any movement from the baby was masked by the placenta which acted as a barrier/cushion. So I couldn't feel a thing a until bub was strong enough to make me feel it through the placenta.
If you don't feel anything by 24 weeks then you should contact your doctor. But is perfectly normal to to feel anything this week so don't worry x
