The millionth "is this a yellow belly?" thread

Hey there, I'm pretty new to the forums and breeding ball pythons. I've read probably all of the other threads about identifying yellow bellies here, as well as on other websites, and watched youtube videos. But I've seen so many variants that I'm still having some trouble so I hope there's someone out there that won't mind chiming in here. This was my first clutch and the pairing was Pastel x Pastel coral glow possible yellow belly. I've got two pastels that I will be posting pictures of below. Hopefully they're clear enough. I sorta doubt they're YB, but I figured it wouldn't hurt to ask... Thanks in advance for any answers!

If it does have YB, then it is not expressed very boldly. I believe that is a nice Pastel.

I had a feeling. Thanks for answering. :)

The second one looks YB
