Okay so I'm 18w today and I've not felt anything at all this whole pregnancy, not a flutter or a kick. Even lying on my back drinking a cold drink etc I still haven't felt anything. I have my my 20week scan in less than 2 weeks and I'm really nervous incase something is wrong! Anyone else not had any feelings at all? I'm freaking out 😔 x
