Hi
i don't think the baby is hurt, maybe
he/she is the one who did it

,
maybe while you was tring to sleep on your
side his/her head was laying on your hipp
or so... I still think you should at
least call the doctor just to make sure
... I am 32 weeks right now and all kind
of wierd things happen to me and I went to
the doctor every time, and of course he
said - and I hate that - " it is normal "
.... Stuff just happen.... Don"t worrie
