Lower back pain what should I do?

I just turned 25 and I’ve been having some lower back pain. The cause was from a few weeks ago I was laying down on my stomach for long periods of time which I don’t normally do but the few times I have in the recent past it has caused some lower back pain/strain but usually goes away within a week. I was laying in my stomach for a really long time this time so ig the effects were multiple, I read online that laying in your stomach messed with the alignment of you’re spine so it’s not good to do. Issue is the pain has lessens significantly with stretching and stuff but it is still there if I bend over a certain way or am hunched over for to long while sitting. Before a. Few weeks ago I never had these issues, is there anything I can do to fix things and get to how I was before I’d rather not have this be a permanent issue I usually try to take care and watch my post so that I wouldn’t have back or as I got older 😭
