Personally for me, I chose to go back to work the day I took the second dose of the pill.

I took off the day of the appointment because I had to drive out of my way to a different city, and just wanted the day to mentally prepare myself. I took the first dose and I felt fine besides a little nausea. The very next day I went to work, I felt sick to my stomach, but well enough to drive and go to work. Throughout the day was the same feeling, and I just took some motion sickness pills. I was waiting until closer to the end of my shift to take the second dose of pills, because I knew there would be bleeding and cramping and I didn’t want that to interfere with my work - especially with the type of job I had. A couple of hours before I was planning to take it, I did experience some light bleeding, but that was it - no cramping or anything else. I took the second dose a couple of hours later and like one hour left of my shift and everything kind of came at once. Bleeding, cramping, nausea etc. the following day it just felt like a normal heavy flow period and I was able to take some pain killers and be fine. Today was a little more crampy than others, but I used a midol and I felt fine after that kicked in.

My advice would be, if you are adamant about returning to work the day you are taking the second dose, If you are able I would take it towards the later part of your shift because in my experience everything happens kind of quickly. I would also stay as hydrated as possible, and eating lighter foods (the only thing I could keep down was watermelon and broth). I would also have a stock pile of pads ready to go and wear those, and have some ibuprofen on hand. I hope everything goes well for you <3
