For the ladies that had a “period” while pregnant, how much did you bleed?

My husband and I have been TTC for about a year after 2 MC but I decided to stop tracking and just try to go with the flow because I was getting overwhelmed actively TTC and being disappointed every month. I was supposed to get my period 3 days ago, I started to spot and expected to get AF as usual. But I only spotted for a day then it only picked up enough for me to use a tampon once but I had to take it out bc it was so dry that it irritated me and now I’ve already stopped bleeding again..so basically only a couple of days of spotting and now it’s stopped completely. My period has never been this light or short before. I know it’s too late in my cycle for implantation bleeding but could this still be a sign of pregnancy? Or more like a sign of infertility?
