First appointment done 😊

Hi all, finally had my appointment at the fertility clinic. Hubby is away for work. All went well as its the usual standard questions asked. My next step is to have HyCoSy done (dye put through fallopian tubes). Im going away next week. Need a break with everything going on. How soon do you have to have the dye test done as i need to work around my husbands work schedule wih him always out of the country
