Lauren,
I once dreamed my son (now ten) was an egg, which I laid, and that he cracked. Strange and scary pregnancy dreams are normal. Don't fret.
Polgara,
Since you are a FTM, not feeling movement at 20 weeks is probably okay. By 24 weeks, you should be feeling baby. Talk to your OBGYN. You should be getting an ultrasound around now- so hopefully you can see some movement at that exam. FTM sometimes can't feel movement as well.
I am a ftm and am almost 20weeks and I dont really feel any movement either and am also consumed by the same type of thoughts as you. I worry a lot
Im sure its normal, some women if they are FTMs dont feel movement til as far as 24-26wks. I bet you will feel a lot better at your appointment/US! Good luck!
