So confused

Ladies my body is playing mind games with me. For my last cycle i posted that it didn’t feel like a period I had no period symptoms at all and my period usually is pretty heavy. That last cycle it lasted about 4 days of jus extremely light pink period. You could only see it if i whipped. 2 days ago I took a pregnancy test and that same day i got my period again. (Once again extremely light pink and only visible if i wipe but this time i did have cramps and bloating like I usually get on my period. Yesterday I had no blood at all even if i wipped and this morning again no blood at all. The test I did 2 days ago was negative so I really dont know whats going on. Have any of you experienced this?
