I've been sleeping slightly on my stomach for the past week, and I end up lying on my side and accidentally leaning into my belly. In the process, I wake up because my belly hurts. The sleep has become bad all night long, it pinches me, and my belly protrudes. There is only a screening in 10 days. First of all, I wonder if I am hurting the baby when I lean into my belly. And secondly, I think that my belly hurts because I press it down when I lie down, what do you think about this?
