Periods not the same since

Claire • 2 MCs in 2014, hoping for a sticky bean third time around, due Nov 2015 🙏
Has anyone else experienced their periods not being the same in terms of flow since a mc? I've had 2 mc's since April and the first 2-3 days are really heavy flow compared to what I used to have. Plus they're a lot more painful too. I had a D&C so I know all the tissue has gone; does it take a long time for things to settle back down? x
