Hi Katia,
You'll have to check with your oncologist about that. I know that mine is heavily booked so it might not be easy to change. I'm on the same Docetaxel/Cyclophosamide cocktail as you and I feel pretty good for the first two days and it only really hits me on the third day. You might be OK for your niece's wedding. Definitely talk to Onco for advice. I think white blood cells are still up at this stage too, they're lowest at around day 10. Just remember to pack anti nausea tablets and some claratyne in case. I have my last chemo on the 21st Jan, woo hoo!
Good luck,
Ingrid xx
