When did you get a positive test?

I have a friend who says that she kept getting negatives until she was already 3-4 months along. It happens 🤷🏻‍♀️ she also has PCOS so I’m not sure if that affected it. Now we have a mutual friend who is trying to get pregnant and asked us when we got our first positives, since she was due for her period 2 days ago and still is testing negative. My friend is absolutely convinced that it’s rare to get a positive as early as a due period simply because she didn’t get hers for so long. I mentioned that I got mine at 11dpo and my friend said something along the lines of it being because I’m so fertile and that most people don’t get positives that soon. So I’m just curious when everyone got theirs.
