Right, as the others have said, take it asap. Don't worry, take your shot and make a note on the calendar for next week.
You can take the shot as soon as you can.
It wil be OK.
Once it seemed like my meds were arriving late by one day, and
I was told just to take it the next day and it would be fine.
Thankfully, they did arrive on time, but my NP said it would be fine if I was forced to take them one day late.
Reva
