I dunno.

How far long are you?

Four months

Well I doubt your sleeping habits are being of your baby moving, if you can't feel it. It is just normal to have disturbed sleep when you are pregnant. I will be 31 weeks tomorrow, and I find it uncomfortable laying down so its hard to sleep. Try laying down 30 minutes before you intend to go to sleep so you have some "wind down" time.

Ok...Can stress do anything to the baby now that im 4 months?

Yes, you need to be in a low stress enviroment, I am staying with my oldest sister, my brother in law and my niece right now because my 7 year old brother has fits where he hits and kicks and I was not only being stressed but I was worried about my stomach being hit. Stay as low stressed as possible!
