When does everyone start testing?

I'm anxious and excited! I'm just one day late for AF... when would you start testing?

I did have a colposcopy on Tuesday and they tested me prior... it was negative. My Dr. did make a funny comment when I ask when I could use tampons since my period was coming soon 🤔

(Sorry, I'm terrible at grammar and typing.... hope this isn't too annoying to read)
