Lol il start again.
I didn't feel many movements nearer the end of my pregnancy. I kept worrying because I'm a large lady.I could tell what position my baby was in, at times he would move if I poked gently but other times no reactions so I figured was on a comfortable position or facing my back and kicking where I couldn't feel it.
The baby could also be going through a growth spurt, they are putting on all the weight the lady trimester and they say reduced movements because of how big the baby is on the sac.
The doctors recommend feeling at least 10 movements within a 2 hour radius, normally when baby is active or you can drink cold water or a fizzy drink and lie on your back,that normally gets the baby moving and awake as well.
Sorry to hear about the constant headache,I also had that and no paracetamol could touch it so I spent most my time in bed. I can't do that now my son is here so if it happens next pregnancy I wouldnt know what to do so bless you
Take care x
