TTC fertility waiting times

Kay

Been trying for a baby for two years, I have been diagnosed with endometriosis, we have finally got our first appointment through to speak to a nurse from the fertility clinic, I'm just wondering/ been inpatient what are people's experiences on waiting times after first appointment/ timelines of treatment starting we have already had blood test swabs and semen analysis done any help would be appreciated (we are having treatment on the nhs through Yorkshire fertility)
