Im not going nuts am I?

So I have a 10 month old babygirl and she is still breastfeeding. I haven’t really gotten my period. August 3rd I had some really little pink spotting and brown spotting for like a day and half and that was it. Only signs I was getting was my boobs hurting, not because of breastfeeding just achy like on a period. So I took a test nothing came up. Went to bed got up and look seen a very faint line. So took another 2 tests came back later same thing? Tried a clear blue and same thing. So I just want to post and make sure I’m not crazy lol my husband sees it too. First time this happening to me. I mean I figure I am because the other tests I’ve taken just negative no faint lines. And with my 2 kids just bold positive tests. So is it because I’m super early or im I just crazy?? Lmao! Can you ladies help me out please??
