It seems to be very common for (hypo)mania to end in depression but not really so much for depression to end in (hypo)mania. I think everyone is different and for me each episode is different. One time (about 20yo) I went about 10 years without symptoms. Within the last year, I had hypomania for several months (when somebody brought it to my attention), then mixed episodes for several months, and am now in mild depression. I agree, however, with previous responses that you probably could use a mood stabilizer and/or increase the Latuda.
