how many times a day do you pump?

S ⭐️⭐️⭐️
I pump twice a day since I got back to work. I wake up at 5 am and that's about the time my baby wakes up - I nurse her, then I'll nurse her again around 7 to 7:30 am before I leave for work.
When I get to work, I pump at 10 am then at 1 pm. I try to pump at 4 pm but thought that I'm leaving already 5:30 and be home by 6 - if I pump at 4 pm, when I get home baby wouldn't have enough breastmilk.
Thoughts? Do you mind sharing your pumping schedule?
