If this is your first pregnancy you might not be feelin baby yet! If you're really worried, like I was, I'd recommend purchasing a cheap 20$ doppler to settle your fears :)
I'm 21 weeks with 2nd baby and haven't felt kicks either
I am on second baby i felt baby at around 18 weeks but my sister in law is on her second and only felt baby move around 23 weeks. I think it's different with everyone
I started feeling the baby move around 17 weeks but doubted it because many sources say 20-24 weeks for your first. But at my 20 week ultrasound the doctor said I should feel movement based on where the placenta attached. Apparently the placenta's placement has a lot to do with when you feel the baby, and it is completely random. She said the placement doesn't matter at all from a medical perspective so there is no need to worry. Good luck!
