Implantation bleeding?

So I’m currently 10dpo and yesterday I saw a very light pink in discharge. This morning when I woke up to use the bathroom I saw some light brown kinda pinkish bleeding/spotting. It was like a good amount but has the day went on it was lighter in color and the amount. Been cramping on and off lightly since. It’s four days before AF. There’s no other symptoms, other than my breast feel like pins and needles since yesterday. I was pregnant recently but the baby heartbeat stopped in February at 7 weeks so I’m trying to stay calm until I need to be excited.
