Need help please (TMI no pic)

Vic(Tori)a • Just trying to make sense of this mixed up world we live in 🩷
Alright so I started spotting light pink June 9 (5dpo) and it continued and eventually got darker on the 16th so I thought I started my period early. Bleeding wasn't heavy, I used maybe 2 tampons a day and when I took them out it was mostly reddish and brownish blood. That lasted 3 days, ending on the 19th. My period was due the 20th. Nothing yesterday and now today I've had pinkish again when I wipe.. I'm so confused as to wait going on.. Has anyone had the same thing happen and been pregnant? Any help would be greatly appreciated, thanks!
