I think its a load of baloney myself. I didn't have any m/s at all - and my baby is fine! Yes I have had one m/c but who knows what caused that? The heart had developed but it just didn't start working - my HCG levels were fine.

My mother never had any morning sickness and had 3 healthy pregnancies. Both of us get very little PMT or period pain so I just think its how your body responds to the hormones more then anything.
