Period

Hey everyone my period is typically always on time every month , typically always 3-4 days no longer than that other than some spotting here and there I call it the “left overs” but this month day 1 and day 2 regular blood flow but today just some spotting , when I wipe there’s still some (sorry for the TMI) but I’m the type of person who starts to assume crap so I worry , I’m TTC too so I start to freak out something is wrong with me , this has happened before but not often anyone else have short periods 3-4 days and on day 3 sometimes not much AF?
