Morning sickness- coming and going

Laura
Is this normal? I was really sick all day long for about 4 days then nothing. I've felt ill but not actually been sick. I'm feeling anxious as lots of people are posting saying that morning sickness shows a healthy baby. My Mum had no morning sickness with me so I'm pretty sure it doesn't matter. I keep feeling strange but I think it might be in my head. I've had a few light cramps but they feel like my stomach rather than lower. I've had no other 'bad' symptoms. I'm still knackered and my boobs still hurt. I just wanted to know if anyone else's sickness seems to have gone? XxX
