Yoga during pregnancy at home videos or app

Sab🦄 *

Hi, I would really like to to some light yoga at home to get through back aches and slight nausea.

I am 6 weeks pregnant. Do you have any recommendations of yoga apps or other types of easy exercise? I follow yoga with Adriene, but there are few pregnancy videos on her channel.

Also do you have any recommendation for books about pregnancy?

Thanks!
