If you are taking Spiro, it is not surprising that your potassium is on the high side as Spiro increases potassium retention. Spiro also increases sodium excretion so that you may start craving salt to replace the increased loss of sodium in your body. Eat more salt, when you crave it. Drink as much spring water as you want, avoiding drinks that contain a lot of potassium.
I wouldn't be concerned about your T having increased, it's still quite low and besides. Spiro also blocks some of the T, the test does not take that into account.

If you are taking estradiol orally, SHBG is also raised so that a significant part of the T that was tested is bound to SHBG and cannot act on tissues.

Increasing E will further reduce T by reducing testicular production of T and opposing its effects in tissues. So, no worries there. Most importantly, focus on results. If you feel good and you are feminizing well, then that's what really matters in the end, isn't it? Nice numbers and all don't guarantee anything...you want actual physical and psychological results! If these are good, then you're good.
