HSG Test (DYE TEST) The procedure goes?

I have been advised to go for a HSG test. I'm 32 and married for 8 years and trying for a baby since 6 months. I stay in Noida and it's really hard to find a centre that conducts HSG and is a good one. Im saying this since this test has cons of getting infection and I dont want to make a decision in a hurry. - Also, what day should I go for the test after my period? -I want to know should I go for HSG with or without the anaesthesia, as I'm really worried if I can tolerate the pain or not. I have chocolate cyst on my left side, which is why I'm unable to conceive naturally. -I want to know whether the gynaecologist who conducts the HSG test helps you in understanding before the test or not, as I'm very confused as to what and how the procedure goes?
