implantation or period????

i’ve taken 5 tests and they have all came back positive but last night i started to bleed it’s a mix between pink and red and it’s a lot thinner than my period so idk what to do. right now would be the time baby is implanting in my uterus but the bleeding is more than spotting. i have a lot of symptoms ,such as,sore breasts, nausea,insomnia, fatigue, constant need to urinate,mood swings, increased smell,bloating(i have never bloated when on my period ever).any help?
