how to alleviate back ache and side pains?

I'm 17 weeks and 2 days and today my back started hurting and lower belly or more like my hips/sides were hurting as if the baby just grew in a blink of an eye lol
Is there anyway to alleviate the aches alittle when it comes?
Only way I found that helps is kneeling on the bed like when you pray and letting belly hang alittle.
