First PP AF

So I want to know others experiences on their first pp AF. I’m 12m pp and I breastfeed. In December I thought I got Implantation bleeding, I had spotting but enough for a pad but not enough to fill it for 2 and 1/2 days and it was inconsistent. Then I had nothing in January. I tracked OPKs got my solid smiley on Jan 31st. I BD 3x every other day of my fertile week. Hoping for baby #2. Then at 7/8 dpo I woke up to dark red bleeding, and I thought oh, I am finally having a period. It started nothing like my usual. I used 2 tampons that day, normally my first 2 days are heavy heavy. So like 4/5 tampons. Then yesterday, I never fully filled a tampon and I used 2. Spotting overnight. And only spotting when wiping now. Light pink. Nothing on panty liner. Today would be 9/10 dpo. I took a IC and FRER, both confirmed neg on here. Any similar stories or advice? I really want baby #2
