So I'm 16+6 and I started feeling the baby at 14 weeks it was only flutters and I could feel them once every 2-3 days but when I got at 16 weeks I used to feel it a bit stronger once per day for the first 3 days and then nothing it dosen't matter what I eat or if I lie down for 2 hours and wait I can't feel any thing and I'm freaking out! there is no other unusual thing with my pregnancy no bleeding no very painful cramps nothing I just cant feel the baby for 3 days I have an appointment tomorrow but If someone of you can tell me something to ease my mind it will be nice coz it's really scary I'm thinking that there could be something wrong and that the baby could even be dead inside!!!!!! so plz help me!!!!
