First postpartum period?

Kayla • Happily married, 2 beautiful little girls, 1 handsome little boy and 1 angel baby.

Ill be 6 weeks postpartum tomorrow and wondering if I have already started my period. I noticed at about 4 weeks my PP bleeding had started to become very light and by like the beginning of week 5 there would be nothing all day but a little spotting. Well this past Sat 22 I noticed bleeding again but it was more brown than red. Now its like a real red and the flow has definitely picked up. I have a 7 year old and a 3 year old at home and dont know if im doing too much and this is PP bleeding picking back up or if its my first period. I have never done this with other 2 kids. I go this Friday for 6 week check.
