Posted about this on MyChart & my PCP got back to me the next day. Her suggestion is to put a new patch on and see what happens the next couple of weeks. The altitude and heat may have contributed in her opinion (+ dinner wine, which I don’t always drink but did in CO). She offered me an earlier appointment than the 8/13 one I already have. I’m going to try her suggestion. . . . part of this is about being grateful that she’s on my team. I ask; she listens & offers her guidance, always making clear that the final decision is up to me. I trust her judgment, and greatly appreciate that she listens well. If headaches return, I’ll go back to the estrogen/progesterone idea. If not, interesting, and good.
