Were 3 laser sessions enough to get rid of hair down there?

Didn’t want to fully get rid of hair down there, but worried that I went too far with 3 in my bikini area. Had 1 session 2-3 years ago, then stopped. Had another in June. It grew back, but kind of patchy and less full. Still had the triangle. Decided to do 1 more session in late September this year and now I’m worried I’ll lose the triangle.

For reference I have dark, coarse, thick hair. Light skin. I’ve had 11 sessions on my legs and some hair still grows. Just worried I went too far.
