Belly/back pain

Heather • ⚓Navy wife💙 💛preemie/nicu momma💛

So I'm 23 weeks in 2 days and have been feeling a bit of pain in my belly and back. To the point where I have to sit/lay face down booty up to try to relieve it even though it doesn't. In my back it just feels like it needs to be cracked or something but I haven't been able to yet and belly just always feels like I've ate too much, like tight feeling and so much acid in my throat even with tums. I guess I'm just curious if anyone else has experienced this? Like what do I do to relieve myself? Is it just pregnancy? Lol.
