Very crazy weird! Please help

Ok this will be a little long but I have to tell the entire story. I've been off bc for two months. So I know my body is still recovering. We are ttc but not expecting anything for a little while bc of the pill. This month 9 dpo I had very very light spotting (I thought IB) so then 11 dpo same thing but maybe a little tiny bit more. But again 12 dpo. But just once a day each day. So christmas day 13 dpo I tested bc I thought it'd be an amazing Christmas gift. With in 30 seconds there was a faint positive it was faint but still there. So I waited 6 hrs and tested again. Didnt drink much and didn't use the bathroom in between and again faint positive. This was at like 11 am. Around 2 pm christmas day I stated bleeding it was still light but it was red and not like what i had the days before. But around 5 it seemed to almost go away. So I assumed af was starting and blamed the bfp on the new curve frer test. I have read that they give a lot of false positives. So around 530 I used the old style and again faint positive. Well the bleeding was still kind of there but not like my normal period. So the next morning still not much blood so I tested with clear blue and again a faint positive. So at this point I'm assuming chemical pregnancy. So day after christmas the bleeding got a little heavier but nothing compared to a normal day two for me. So this am I wake up and yes I'm bleeding but its so much less than I'm used to. So I took a test thinking if its a chemical the line would be the same or lighter or gone. On the old style frer it was darker! I'm so confused. I know I shouldn't be testing so much. But I don't know what to think. How would it get darker? Please anyone have any experiences like this? I am just so confused.
