As long as you notice the buds swelling, you should be OK.

And bear in mind that the timing of budding varies quite a bit.

I have various palmatums opening leaves now, and a tschonoskii, but griseum,
for instance is later and its hard to tell if the darned thing is still kicking
unless you scratch the bark to see if it is green underneath.

If you are worried about it, scratch the bark with your fingernail - green
cambium means you are still a going concern.
