Any EBF moms with intermittent light pink spotting??

I think my true PP bleeding/spotting ended around 8.5 weeks (it trailed on lightly for a while). But now at 10 weeks PP, I’m having light, bright pink spotting once a night the last two nights?? The color is different than my PP spotting and it’s literally one wipe or a few spots on one panty liner TOTAL, both times around 3:30 am. So maybe it’s related to baby’s longer sleep time? Anyone else with this?? I’ll call my doc on Monday, but Google is making me worried...
