I'm new to sewing, I only got my machine a little less than a month ago. Everything was going great until recently I noticed the stitches on the underside of the fabric were sort of... waving? I first noticed this when I had to switch to a sturdier thread, so I assumed that was the issue, but since then I've been using a thinner thread and I still have this problem.
After some googling I thought it might be due to the tension being off but what i'm getting from my machine doesnt quite match up with the pictures of too tight/too loose tension, and I swear I've tried every tension and the bottom of my fabric looked similar each time. It's driving me nuts
So I was wondering if any of you might know what's going on?
here are a couple of photos:
And another on paper so I could try to get a better idea of what was going on:

I don't think machines suddenly change thread tension all by themselves much, so a good chance you are doing something just different.
Things to check:
#1 Make sure you don't have made on purpose "Glaced Hand Quilting Thread" for only hand quilting use, wound onto your bobbin by mistake. That thread looks pretty stiff and wirey to me. And not what real garment sewing thread should even look like.
If you got all real normal garment sewing thread, then:
Un thread whole machine, make sure top tension device is still set at middle mark or mid # or what ever marking it has for that. Rewind a new bobbin, and make sure when it's wound, it's wound tight on there not all loose and loopy. If you have to use your fingers while doing that, just do it. Then make sure when you put that bobbin in, it's feeding off in the correct direction, most times on most machines that would be counter clockwise. But check your book to make sure. Then make sure the thread is really though the tension slot in your bobbin case right. When you tug on the end of it afterwards, you should feel resistance there. I bet you don't right now. Then just re-thread the top thread and try again. Just doing all that stuff, would even cover a multitude of possible things.
Since doing all the rest, stick a brand new size 12 or 14 needle into there too.
Other things that might make that happen I guess, might be bobbin tension held wide open, because you got a piece of lint stuck in it doing that, or you lost your whole bobbin case screw and it just fell out of there, (I don't think that happens all by it's self much though) or maybe even needle hits on your hook, that maybe catch some thread with each stitch, but kind of unlikley and I think more it's something you are just doing different than when it just worked a lot better instead. You could try all those things.

Beauturbo gave you great advice. I think you might not have it threaded correctly. Put in a new needle and match the needle to the fabric (it looks like that fabric would probably do ok with a universal 12 or maybe a 14). Turn the upper thread tension to a middle setting. Rethread everything following the directions in your manual or look up your machine on youtube. Thread with the foot up-this is very important or the top thread does not catch in the tension disk properly. I hope you didn't mess with the bobbin tension-that is probably ok. If you have 2 colors of thread and a plain fabric, that will help you know what tension is off. Post more pictures if you don't get it to work. HTH
