Anyone else experiencing increased migraine while on Exemestane?

I have been on Exemestane for years (also Ibrance) for Stage 4. It has been working with a few small setbacks. However what started out as a migraine headache for a day every few months has increased to every 10 days to 2 weeks with days to recover. They have ruled my life in addition to all the other side effects of treatment. My oncologist says it’s not the estrogen blocker but everything else in me says it is. Anyone else have experience with headaches/migraine while on these drugs and will s change in meds help?
