I am 9 weeks pregnant.heard baby's heartbeat @ week 7.felt nausea few times while brushing.last couple of days no symptoms at all.should i be worried?

No, lucky!: Some people have few signs of morning sickness, some have none. I couldn't stand the smell of bleach and that was all. Consider yourself lucky! and may everything go as smoothly. Having babies is easy for some and harder for others. My mom always said she would rather have a baby than go to the dentist!

Nausea in Pregnancy: No. Not every woman feels sick with early pregnancy and most women who do get over it by the 12th week or so. Being only 9 weeks it's unlikely that you will feel fetal movement yet. If you have no bleeding or pain the likelihood is that every thing is just fine. Check in with your doctor for reassurance. Hope this helps!

Not really: most likely no problem, if worried , please check with your doctor

Probably not: "Morning sickness" doesn't have to occur to have a healthy pregnancy. Maybe you are through the worst of it. If you experience bleeding or spotting, you can be concerned and can see a physician at that point. Otherwise, keep your regular visits with your GYN MD and have a happy healthy pregnancy!
