Welcome Lindaazure! From you pics it seems you are right - you look like 2a/b to me, but many people will tell you that your hair's properties (for example how porous it is) is more important in choosing products than the hair type. But I think hair type is an important jumping off point.

There is a special 2 forum that you might like to read up on. Best of luck with your journey to embrace your waves! I hope to read about some of your experiences.
2/b maybe 2/c. Coarse hair med. density.
Protein sensitive but can use occasionally
Highly porous. Color over grey.
Best 1st day method: Smasters!
Stylers: Mix Curls in a Bottle into everything for shine. Terrible pj
Sometimes try roller sets or use a curling brush - classic glamor.
Every day is a gift
