HELP!! What the heck is happening...

So AF was due to show up today 9/20. It came last night with light pink spotting after sex and then more red spotting today. But the weird thing is my cervix is basically invisible. It disappeared! I didn't think I was pregnant but I'm just very confused on why my cervix would be so high but I'm bleeding. Help!! Its also never been like this before. I usually check just to know what's up with my body. But I'm so confused!!!
