If you want stability you need to change the patch when it is due at the latest, ideally 3 days if yours stick that long, but certainly no more than 4.
When women try to eke out their patches, wearing them longer than the recommended interval, which usually happens as a result of affordability issues or product shortages, they end up with very unstable estradiol levels as that patch stops working reliably and levels plummet.
This can result in a worsening of symptoms, unscheduled bleeding, and for some the impact of a sudden upward swing when a new patch is applied.
Please try to maintain stable levels by being consistent with both your estrogen and if relevant, the progesterone.
Individuals with mood instability can find continuous progesterone easier to tolerate than seesawing up and down.
75mcg is not a high dose unless you are a super absorber. It is not higher than what you would have routinely seen during your menstruating years.
Facial hair can also be a sign of low estrogen relative to androgens, with resultant low SHBG, so more of your testosterone is unbound.
You are lucky to have access to Newson's clinic. I would keep things consistent until you see your provider.
A blood test may also help reassure you that you aren't overtreated.
