Lou- it is so hard to know what to do isnt it. I actully gave up work so I could do IVF. (I had major workforce issues that could not be settled) I dont think I could of gone though cycles and work. I now only work casual and as it is heavy lifting I do not work in the TWW. Being casual it is easy for me to take off. I would just go with what your heart tells you do do. Some girls would prefer to be at work and not forever thinking what there bubs are doing, For me I have a lot of pain Post EPU that I would need to if I worked more regulary.
