Implantation bleeding

So I'm currently ttc after a mc in April. During my first pregnancy I has implantation bleeding but paid it no mind because I thought my cycle was coming. This time I'm paying attention and now have some spotting. It's only when I wipe and the first time it was brown second time it was the picture below. I'm not sure when I od but it would have been the 12th or 13th. I'm on cd 19 with a 28 day cycle. I had cramps cd 18 and today af not due until the 27th. Is this implantation bleeding?😊 thanks in advance
