Just ... Wow. I hope you don't mind, but I'm going to use your boss as a reminder to myself that I should be grateful (and I am, just even more so) that I am in a stable and loving relationship with another adult, and that we are actually prepared and ready to birth and raise a child together. No matter how out of control things might feel at any given moment.
Good luck on your HSG. Mine was really a breeze. I think I had one moment where I thought "Wow, this could get really uncomfortable, and I'm not sure how much longer my poker face can hold out." But that was also the exact moment when it was done. And, FWIW, I got my BFP on the next cycle.
