Need Advice!

Nervous to shoot my first wedding in less than a month now, although I’ve second shot tons. For some reason, I’m mostly anxious about the timeline! I’m used to being directed by the lead, and worried that I’ll fall behind somehow or run out of time for certain shots.
I also haven’t heard back from the planner about timelines/ info. I obviously haven’t had much interaction with planners yet, is this normal? And should I expect that the planner will kind of direct me throughout the day? I think not hearing back yet is what’s causing most of my anxiety! Would appreciate any tips on staying on course during the day 🩷
