I asked my doctor about that and she told me it really doesn't matter, sleep how ever I'm comfy. Left, right, even flat on my back if I rather. Aslong you get your sleep that all that matters. The whole " sleep on your left side or baby won't get enough oxygen/blood flows better " isn't true. Just like the one of laying flat on your back is supposed to compress a major artery
I try and sleep more on my left but it just doesn't happen and baby doesn't like it as much either so I'm usually on my right
I sleep on both. I try to sleep more on my left but sometimes it just isn't comfortable
thats how i feel .. im more on my right side than on my left , and baby likes better that way too ! i dont know if its good ur bad but its more confy
