Hello, I've found that pregnancy is not necessarily about good things Aside from many other problems, it turned out that sleeping is a pain. Both literally and figuratively. I use an old innerspring mattrss, and it's sagged, and that's how I know what the problem is. What I don't know is how to fix that. I think any new mattress can solve the problem but what if it won't? Maybe, I need something specific? Something firm or something soft? Wehat do you think?
