help please

Brooke • Rainbow baby named MacKenna ♥️ married to my high school sweetheart

So last night I was called into work for a grave yard shift and I was went to the bathroom and notice

there was some blood on it so I checked on my app (it was say it was just now but it was 3 in the morning when I was working but still accurate

And I'm thinking to myself. if my "week" is already here why am I spotting? please don't say go to a doctor. I want to know if this ever happened to any one?
