Sleepin

I'm having trouble falling asleep at night cause sleeping on my side hurts my back cause I have to force myself to sleep on my

Sides and not back which puts a lot of stress on my back. I never slept on my side before being pregnant which make it super uncomfortable to sleep in my side know. Before getting pregnant I slept on my stomach or back cause it's the most comfortable for me and I get a better nights sleep and I wake up also pain free. I would sleep on my back but I've heard it's bad for that baby and I don't know how else to sleep. I don't have a pregnancy pillow and I don't plan on getting one either. I don't have enough money in our budget to spend 45 dollars on a pillow nor do I wanna spend more money than I have to.
