Pregnant not pregnant?

So this whole time I’m thinking I’m pregnant bc I missed my period and I was feeling “symptoms” but i took a test and there was a slightly faint line but today I got my period I’m guessing or I’m not sure if it’s implantation bleeding? Tmi but the blood was more watery if that makes sense, usually it’s somewhat thick bc it’s blood but idk, what do y’all think?😕
