what the heck is going on

Baby girl is3 months tomorrow. It's been 4 hours that she's been awake she's crying and yawning but doesn't wanna nap. She did this yesterday too and had lasted 6 hours before finally napping. She's nvr done this before and I could always get her to nap within 10 min 😰 wonderweeks isn't  telling me anything useful. Anyone else's baby doing the same thing?
