I’m about 5dpo—please read

So at approximately 3-4dpo I started coming down with a sore throat, as it hurts to swallow...also, along with some congestion and mucus.

So, to me I didn’t think anything of it. I really did think it was probably just a cold, so I went to the doctor today to get tested for strep and it came back negative.

Now I really can’t help but think if it’s a good sign even though symptoms can’t appear so early, let alone before implantation.
