Just started bleeding again 6 weeks pp?

I’ll be 6 weeks pp tomorrow (And breastfeeding) and I just started bleeding again. I stopped a week ago the day of my pp appointment and then tried to have sex a few times after that and it hurt too bad for him to try to go in so we didn’t end up doing it any of those times. But 2 days ago I ended up being able to use my dildo and had an orgasm (for the first time in 8 weeks!!!🥳) but then after that I guess it started the bleeding again, enough to show up in my underwear. Is this normal? Also when I was bleeding before it smelled disgusting but the smell is gone now.
