Yes, give it time, and follow the instructions about where to place the patch. Basically anywhere the manufacturer says to do it is good, though a) Climara apparently showed better absorption through the buttocks and b) it's true that even the weekly patches deliver slightly less estrogen on the last day or two than on the first day, so changing twice a week may be a good idea.
Patches actually cause so much *better* absorption that there is much less E necessary than in a pill - using hypothetical numbers, a pill with X amount of E is equivalent to a patch with about 1/20th X in it when it comes to producing the same blood levels.
That said, I do think maybe some people respond better to some methods than others, given how often someone swears that injections worked for them but a second person insists pills were better, etc.
