No it can't. Your baby is well protected and you will be fine to lay on your stomach if you really want to - expecially in the first trimester. Once you start to get bigger though, baby will let you know when its time to stop.
I Am 8 Weeks Pregnant Can Laying On My Stomach Hurt The Baby?
It is advised by doctors that you shouldnt. They suggest that you should lay on or left side.
At 8 weeks you probably don't even show yet. I had 3 children I always lay on my stomach until the belly is big and showing
