Confused? And long post im sorry

Okay so beginning of March. March 3rd i bled for like 24 hours. Used i think 2 pads total. Which is odd for me. I usually last 4 days.

Hence me testing so much.

Fast forward to yesterday and today.

I have 2 apps for AF. One i inputed the one day of bleeding as a period. One i didn't.

The one i put it on says AF due the 4th of April. The one without it says it was due yesterday.

I woke up took a test today.

An hour later noticed when i peed i was spotting i said okay im not pregnant. Well 4 hours later. Spotting stopped. And legit only was like 2 quarters size pink spotting on pad. I felt my cervix after i noticed i stopped spotting. It's high soft and closed.

Im SOOO confused.

Any insight on this?
