I don't think it sounds too high, though it really does depend on where you're at in your cycle and as you're not sure, it's hard to say either way. You could have ovulated and be in the luteal phase without knowing and actually be low? Or be at ovulation!
I think blood tests will only be useful once you know for sure where you're at in your cycle and until then I think how you're feeling is a better guide. Sore boobs are indicative of rising estrogen but also a common side effect when you start HRT (and went away for me).
The strange symptoms could also be due to the timing of your HRT not being in sync with your cycle (if you're normally still having one which it sounds like you are). For example if you're unknowingly taking Progesterone before you've ovulated in your cycle, that might throw you things out a bit and cause side effects. In my own experience my body complains any time I try to go against anything it naturally wants to do!
I'd be inclined not to start tweaking anything just yet as that can cause more problems and then you lose sight of what's what, so if you're feeling like you can carry on for a while just see how things go. You might end up getting a surprise period shortly - that happened to me about 6 weeks after starting HRT.
Keep us posted xx
