What is this? A week out from my period

Never had anything like this and I have 3 kids haha and I don’t spit I get my period and then I hush for a week or two sometimes get 2 periods a month

Today I had a tiny little pink light pink spot dr had called to check back about my periods from January and said take a test 😂🤣🙄 I was in there before in sept and she thought I was crazy for getting positive tests 🤷🏼‍♀️
