Trust your body. If it's not comfortable on your left, don't sleep on it. You won't cut off circulation to the baby, it is just supposed to increase the oxygen flow. There is some evidence that the weight of the baby kn your spine might cut off circulation to your own legs,buy obviously if that happens your body will automatically shift position like when you have a dead arm.
Having said that, I've "read" many times about sleeping on the left, but never once has a medical professional ever asked about my sleeping position or advised me to do it. I was on bed rest for 3 months with my first and it was never mentioned.
You can sleep on your right side too..
How far along are you? I always hated my left side and unless I was in for a scan was always told "find a comfy spot and pass out" once I it big enough though I was told comfy was not allowed to be on my back.
Try the couch, I found sleeping on the couch so I could halfway sleep on my back the most comfortable once I or bigger.
I lay on either side and cram a whole bunch of duvet between my legs. My partner sleeps In his own single bed and I share our king size with our two year old even tho his cot is right next to the bed he won't sleep unless next to me! So I have the delight of spreading out with feet in my face no matter where I lie. Also try wedging something like a pillow or more covers under your bump it helps take pressure of the back :)
I'm 16 weeks, I've tried a pillow between my legs which helps a little. I sleep a lot, like 8p-8a but it disturbed, I wake a lot and stay up for 30min plus each time, up to 2 hours.
Try a pillow between ur knees and thighs and one at ur back (no room for hubby) at least if u roll over u won't be completely on ur back goodluck
It takes time, trust me. Took me four months to actually adjust to it. But even now I mostly tend to sleep on my right side
Haha I don't even remember the last time I shared a bed with him it was a few months before I gave birth well over two years go and now he stands no chance of getting back in our bed :) well not until every one has grown out if it.
