Do not decide whether or not to give her something based n what you think she will do or say afterwards. You cant possibly predict what that will be. Decide your action based on what you think is right.
I am hesitant to say that you should give her NOTHING as I dont think that you want to treat the woman you love in that way. I would think something small and thoughtful, like you might give someone at work would be appropriate. Or even just getting one of her favorite foods or something to have in the house around that time.
