So confused

So my dr has decided to go ahead with infertility treatments but before she sends me to a specialist she wants to do a hysteroscopy but said the specialist would probably have to do a hsg... Do I really need to do both? We've been trying for a year an a half with no success, I know I'm being impatient but I'm not really wanting to do the try and see method anymore.. Can I elect to just skip it all and go straight for IVF since that's where I'm heading anyways? This is so depressing I'm losing my mind! Sorry vent over
