Oh dude, you've been here long enough to know that nothing is ever " obvious"! Lol!
I can't tell just from this post when you stopped your AI re your transition from blast to cruise. Nor can I tell from this post what your blast was. Nor can I tell when your bloodwork was done!
My point is, missing all of that important info, would be just a guess so I'm back to my original thought which is, " if you are not feeling symptoms of crashed E2 then don't sweat it.
And just To add to the obvious thingy: I blast n cruise and I ALWAYS am taking AI. Just not the same amount.
