bleeding came back

i’ll start by saying i’m 1 month postpartum as of yesterday. i had an average amount of bleeding the first two weeks and by week three it was basically gone and turned into basically discharge with a slight tinge of pink or red. i stopped wearing pads when i wiped and didn’t see anymore blood. as of maybe 3 days ago, the bleeding is back and it’s red like it’s new blood and enough to the point i’ll have to start wearing pads again. i thought it would pass but it hasn’t. is it normal for bleeding to stop completely and start up again?? i’m not in any pain and i feel fine just find it weird it came back and it’s red instead of brown. i had a second degree tear and a couple stitches if that makes a difference
