Having a hard time with “take it easy” orders...

So, I’m 9wks 2 days and on the appointment the Dr. told me to take it easy due to some spotting.

I’m a VERY active person and also a teacher so I need to be in movement 24/7 and I’m having a hard time taking it easy. I can’t walk slow (even though I’m starting to fatigue) and in top of that, I live in a 5th floor with just stairs. In my job I’m usually from side to side, up and down but that’s how I am... 🙁

What can I do to “take it easy” for my baby’s health? Any advice? It’s haaaaarrrddddd
