Weird period?

Emily • Our rainbow 🌈 baby has arrived! April 3, 2017.
So I had a MC in May. My first AF was due on  June 22. I took a Frer on the 23 and got a vfl.   I then started AF on 24; really strong cramps but very very light flow. I mean, mostly spotting. It was some red but mostly brown and pink. 
I figured it was my AF but today I'm feeling lightly crampy and some nausea. 
Anyone else have something like this happen? 
Any advice?
