Implantation bleeding or something else.

Marie
Today I am 7 dpo and when I went to the bathroom earlier I wiped and there was a drop of bright red blood and light pink mucus with it that was slippery. There's been no blood since. I'm wondering if it could possibly implantation bleeding. I'm not experiencing cramps or anything I'm just really tired most of the time and I usually take a nap midafternoon because I'm so exhausted.This has never occurred and I don't know if it could possibly be implantation. If anyone has any suggestions it'd be appreciated. Thank you 😊
