Hiya
First time round doing icsi I was off for the full treatment process mainly coz I'd had a mini breakdown, not just over treatment but we had a lot of other things on the go as well, for our first fet I only told my boss and knowbody else, I continued with work but unfortunately there were a lot of stressful things going on, they tried to help but I actually think they made things worse, I don't think it was personal they just didn't know how to deal with the issue. This fet was a negative, now I'm not saying I blame work stress but I very much doubt it helped.
So I have one last shot and I've decided nothing is more important than giving it my all, I'm been off sick for a few weeks and plan on staying off until after treatment, my dr is fantastic and has put dibility on my sick line, think it means unwell, it doesn't really go into the ins and outs of it although she knows why I'm off.
Your employer would be incredibly stupid to penalise you for being off sick due to Ivf.
At the end of the day I think you need to do what feels right for you, others may not understand your thought process but that's because there not in your shoes, i def don't think stress helps any of us going through this, but at the end of the day it's a stressful time with added work stress.
Do what you feel is right and take care
