Increasing estrodial patch, how much did you do?

I started. 025mg estradiol patch in May and have been doing pretty good on it until about a month ago. Despite having the Mirena IUD I get a very light period that more recently lasts 10 days and then have breakthrough bleeding. And with it PMS symptoms. I have noticed my joint pain and brain fog are getting worse as well. My gynecologist suggested I could increase my estradiol patch but didn't indicate how much. I just refilled my .025 prescription and was thinking of doing two patches. Anyone else double the dose and find it helped? I am slo on 100 mg progesterone.
