D&E: when does bleeding stop?

SKD • Lost my baby girl at 20 weeks February 2015. Rainbow baby boy born January 20, 2016🌈👶🏼. Early MC May 4, 2017. Second Rainbow baby boy born March 18, 2018!🌈👶🏼 💗Shayla Rose👼🏼💗 💙Royal Holden👶🏼💙 Lucas Stephen 👶🏻💙
I had the procedure Feb. 25th and I have only spotted really on and off for the last two weeks.  I didn't spot Friday-Saturday, so I thought I was done bleeding.  However, I spotted today.  This morning I had what felt like menstrual cramps, but I doubt this is my period already.  It's probably my uterus shrinking.  Is it normal to bleed over two weeks?  I just want it to stop😢
