Anybody sleep on their side after open myomectomy? -my back hurts and I need to rest it

I am not use to sleeping on my back prior to surgery so its been hard. I have been sleeping on my side at times but i wondered if that puts stress on the incision or does it matter at all. I am now 1 week post op after an abdominal myomectomy. Feeling a lot better finally! Did any of u do this. The nurse at the hospital said it was fine but not okay to lay on my belly
