Oh crap @Dandelion. I guess you need to see how you go. I kept hoping I would be able to go back to work then after round 3 (my bp barely sat above 95 on chemo) my oncologist just wrote the certificate until end of treatment. I then chose to use GP for the rest and did a graduated certificate to return to work as I was so physically weak. After chemo I needed about 6 weeks until I felt well enough to return. Many women can do it without problem. Many cannot. Not only could I not physically work but I couldn't mentally work. I needed the time to process this whole bc thing, grieve and deal with my fears...head on.
