Do I have an ab crack or just a random line?

[Sjenson21]

I workout six times a week doing body pump, body attack, combat and grit. I’m 36 and had a baby last year. I’m quite happy with my figure, size 8. Trying to work at my slight jelly belly - took a progress pic and wondered if the line is an ab crack or if this is normal?

The horizontal line is just a fold from where you'd sit/bend over. The first horizontal ab definition you'd see will be the definition at the very upper abs. I have obviously defined upper abs and then that fold line near to where I can just about make out the lower definition line. It gives the illusion of a six pack but it's not one.
