Both of these are low risk for problems to me and the baby and still keeps me active without overdoing it.
Prenatal yoga benefits from the Mayo Clinic:

Decrease the risk of preterm labor, pregnancy-induced hypertension and intrauterine growth restriction
Right now I'm using the Prenatal Vinyasa Yoga video in the middle (blue video). I love how I can determine my pace for a 15, 30, 40, & 75 minute practice depending on the day and how I feel. I'll even start the 75 minute practice and after 25-30 minutes pause the video and start there the next day/time. The other two videos have other options you can choose from as well.
I really like how there are three people in the video doing the poses (one in first, second, and third trimester) so I can follow based on my trimester or my capabilities. This especially helps me from overdoing it or trying to move in ways my body can't right now. The short forms give modifications, labor poses, and yoga practices. I'm really excited to use some of the poses I learned during labor.
From using the videos, I have felt more relaxed and particularly calm about giving birth, from stretching out it has helped my muscles particularly during the night, and I have slept better when I have done some kind of yoga during the day.
