What is going on with me?? second line?

Hey friends! I had my rainbow baby the first week of November.. I got multiple faint positive tests after Christmas along with pregnancy symptoms but my hcg levels were 0.23 I had a very heavy period (my first period after having my little babe) right before these tests. Now I’ve had another period Jan 4-8 much lighter a long with some spotting but back again with a faint test! I’m no longer bf as my little has CMPA which was around 4 weeks. I’m on the patch for bc. Pictures included. My hcg levels are less than 5 according to a recent lab draw this week. Pink dye tests are from dec and blue dye are from now 🥲
