Hi,My I'm 21 years old, my weight is currently 152, I'm 5'7, this is my 2nd pregnancy and I'm suffering from EXTREME back pains, the sides of my stomach hurt, I cramp several times a day, I get really bad headaches, I fell morning sickness all day long, can't eat anything, and haven't for about 2-3 days, and also have a fever. Is all this normal or should I be taken to the emergency room??
