Need to increase estrogen? Change patch more often?

Before starting HRT, my main symptom was extreme fatigue. I started at 0.0375% estradiol and felt better. I increased to 0.05% and felt "back to normal" for several months. For about the past month, I've been so tired again and also sweating myself awake at night again. How do I know if I should increase my dose? I'm on a twice-weekly patch - I was thinking about changing every 3 days to slightly increase what I'm getting and see if that makes a difference?
