Faint lines and implantation bleeding

Af was supposed to start 06/12 today is 06/13, 7 days past ovulation I started spotting bright pink maybe even dark pink but not red it lasted on and off for about 4 days maybe even 5 one of those days I didn’t spot any until maybe later that night eventually the color went from bright pink to light pink to a light brown beige color mixed with cm eventually it stopped and I took a pregnancy test 06/08 I looked very faint so I waited til the first missed day of my period to retest and I got another faint I’ve had chemical pregnancies and a few miscarriages as well the only time I had ever experienced implantation bleeding was the June of last year where my pregnancy lasted for a 3 months (which is longest out of my pregnancies) until I road on a motorcycle and lost it that was 100% my fault and my stupidity I wasn’t aware I was pregnant so yea I know stupid but it happened anyways now this month I know I’m pregnant im taking vitamins and I’m not cramping my back doesn’t hurt so I think I might get to keep my rainbow baby I hope so anyways😊 so lmk if you do see these faint lines just so I have another woman’s judgment I’d appreciate it so much thanks y’all ☺️
