Hi Jane
There are plenty of modifications for pregnancy and at this moment I don’t have photos ready for the web. I have started the wheels turning to get some pregnancy resources ‘out there’. I just won’t be able to do that right now.
You can try a yoga squat for poses where you could be on your belly. It’s great for opening the pelvis. However if you want to simply replace that with a backbend then you could try something else – even do a Standing Bow, an up dog. Anything that works for your body. Let me know what you decide. It will be handy for other pregnant yoginis who want to substitute poses.
Namaste
Gabrielle 🙂
