5w PP period or just bleeding ???

I’m confused as to whether I’ve started my period or not I stopped bleeding at 2w pp I had a vaginal birth w/ 2 stitches. Monday I became 5w PP & Tuesday I started bleeding again. Could this be my period ? It’s not like the periods I had before I got pregnant. It’s a lot of a brighter red color and heavier flow. I don’t go back to the doctor until the 27th.
