Postpartum bleeding

I’m a little over 6 weeks postpartum and when I went to the bathroom I noticed I’m bleeding again, kind of spotting not full on soak a pad bleeding but bright red nonetheless..

Is that normal??

My husband and I fooled around last night and I orgasmed but there was no penetration do I don’t know if that would cause the bleeding . I messaged my dr but I’m nervous that it’s not normal to be bleeding again.. I haven’t bled in 2 weeks.

There’s been no signs that this is the start of my period either
