been sleeping on my left side with pillow in between my legs but woke up feel backache every mornin

My fiancé got me the Clevamama Therapeutic Body and Bump Maternity Pillow. It’s been my best friend. 100% cotton cover and filled with hollow fibre. No polyester like a lot of the Shopee ones do - which means you won’t get warm in your sleep. 👍🏽
