Do I have to wait a whole cycle to get fertility tested?

I thought today was gonna be day one of my period because I had bad cramps but I only had brown spotting and it’s 8pm. Which means that technically tomorrow the 10th will be day one. But I wasn’t able to make an appointment for the clinic I’m going to until the 13th which will be day four of my cycle and I only have 3 day full flow periods with spotting afterwards. So is there even a point to going to my appointment ? Can they do anything?
