I have two days a month - day 1 and 2 of my period - where I feel like I'm going to die. I have to down tools and go to bed.
This has only started happening the last few months and these days have always happened at the weekend or days I'm WFH so its been okay so far.
But I'll be back in the office a lot more soon, and there will inevitably be days that I need to bail.
Should I tell my line manager now, ahead of time that this is likely to happen?
Or just take sick days as/when the situation occurs?
Should I get a note from my doctor to say what the situation is in case I get in trouble for missing days several months on the bounce?
Really appreciate anyone's insight into this. Thank you.
