Hello,
Im Khaira from Estonia. Im an oriental dancer and teacher. I have made a university research "Oriental Dance During Pregnancy". Its a 45 page long work made thanks to the cooperation of Estonian and Finnish oriental dance teachers who have had the experience of dance and carrying a baby at the same time. Also two mid-wife's have participated with their thoughts related to the subject.
Unfortunately it's only in Estonian at the moment.
The main points You need to consider are:
1. Oriental dance is safe during pregnancy ONLY if You have prior oriental dance experience. This means, it's familiar to Your body and You have adapted the correct body posture.
2. Correct technique is used during dance.
3. Listening to Your body. This sounds like a big cliche, but this its the best advice. For many dancers it means making the amplitudes of moves smaller and doing exercise with half less energy. It's still enjoyable
4. When it comes to the baby during dance, don't worry if she moves more active or doesn't move at all. They usually are still more active, but Your concentration on dance makes You notice the baby less.
5. Contractions are also normal while dancing. Same contractions could bother You without the dance as well. If it becomes more frequent, it's better to consult a doctor.
If You have any more question conserning the subject feel free to send me a private message.
With Regards,
Khaira
