Implantation or just not pregnant?

I stopped taking my birth control last month. My partner and I were trying to conceive. My period is 5 days late now and I took 1 test over a week ago it came out negative Another a couple days later which was positive. I woke up today and had very light bleeding. Blood only appears when I whipe usually. I have a few darker colors but looked in more clot form (sorry tmi). But never enough to have to were a pad. Normally is light pink and sometimes a dark red. I don't know if it's implantation or if it's a miscarriage or just my period I took a test about 10 minutes ago it was only a 1$ test tho, and it was negative. So I'm highly confused and want to know what to do. Any advice would help
