Strange period. Can anyone relate?

Cobromo
AF was 2 days late after having some brown discharge on the day she was due. Bummer. AF ended after 4 days which is very odd for me, I'm always a solid 6-7 days. Today, CD 8, I'm having some spotting after 4 days of nothing. I'm also having some very very mild cramping. Has this ever happened to anyone? I'm trying not to read into it too much but I would appreciate insight! 😊 (Also posted in General TTC)
