Confused 🤷‍♀️

Ai

I’m Currently still breastfeeding my son and haven’t yet had a cycle.. but I’ve been feeling off so I decided to do a pregnancy test which came up Faint positive (I also took another that afternoon which also came up positive too)

This morning I took another assuming that it would be darker and it was completely negative..

I’m super confused with what could be going on, any ideas?
