Brown bleeding/ Early Symptom?

So it’s gonna be long and please save the nasty comments cause I will delete them I just want advice..

Anyway! so Sunday the 22nd I started spotting very light pink, the next day I start bleeding red. I have a 13 day LP so day 14 is technically my CD1 for me. Well cd 1 I start bleeding and I think ok my period is here right on time smh anyway that same day my period went from bright red to very dark brown and then stopped. I bled for maybe 4 hours and it was a light bleed. The next day “CD2” I wake up and see no blood on my undies until i go use the bathroom I notice red blood again just while on the toilet. I pop a tampon in and say it’s my period being a bitch ok fast forwards few hours I go to change my tampon and I see only dark brown spots on it and it wasnt old dried blood (tmi) it was fresh brown blood. I didn’t bleed the rest of the day.

Today is technically CD3 and I have absolutely no bleeding no cramping nothing. Ive been reading that brown discharge could be an early pregnancy sign. I had 2 faint positives on blue dyes but I figured they were false positives since blue dyes are notorious for them. Has anyone that has been pregnant experienced brown bleeding in early pregnancy that thought it was a period. I’m confused and my order of preg tests won’t arrive until next week. I’d really appreciate advice and help ladies!
