Idk what’s going on!!!

My glow app says I’m suppose to get my period on the 27th which I didn’t get it. I took a test and it was negative. Took another one last night I didn’t see a line,but when I re looked at it today there was a faint line. To be sure I retook one today but didn’t see a line. After I went to the bathroom and wiped there was blood and it was light pink so I was like ok I got my period. A hour later I went to the bathroom and wiped but there was no blood just some creamy clear mucusy stuff... does anyone know what could be going on???
