Does this mean ovulated today?

What do you think did I ovulate today? I had a HUGE nausea rush over me today mid morning I had to sit down for a few minutes because I felt I was going to be sick. Got my first high reading last night and then got my highest this morning and then it’s going down now when I recently did another. Did I catch it and it was today??
