Does this seem like postpartum period?

8 weeks postpartum and exclusively breastfeeding.

I had egg white discharge for 2 days then brown discharge for 2 days then red discharge for 2 days, now it's brown again. It's been very stringy this whole time and super light. I haven't had any cramping. It's been about 2 weeks since bleeding and spotting had stopped. Haven't had sex or started any birth control yet.

My periods are usually very heavy the first 2-3 days with a lot of cramping.

I know every pregnancy and postpartum period are different. Just wondering if this could be the return of my cycle or just more postpartum bleeding. I'm 42 and it's been 16 years since my last baby 🤷🏻‍♀️

Thanks for your input and experience!😊
