Idk what’s going on 😫

Whitney • Girl mom 6/20/22 💗 Baby boy due March 2024 💙

So I had a faint positive frer on Sunday. Monday and Tuesday the faint line got darker and pinker. Wednesday and today when I tested in AM, the line is more faint. I can still tell it’s pink but what could be going on?? I had a tiny bit of brown spotting last night but nothing this morning. BBT is still elevated, sporadic mild cramping but doesn’t seem like period cramps. I’m still testing negative on digital tests. Chemical maybe?? 😭
