Hsg/Clomid

Li

I am currently 33 and ttc #1. We haven’t been at it too long but doctor is proactive and tested me ( all bloods good). Now I’m going for an Hsg and then she said I could start Clomid if I didn’t get pregnant after Hsg. ( said That’s fertility would increase )

So I’m petrified after reading about Hsg and even Clomid. Any real advice on either ? And hopefulness I should have after either ?
