Any help appreciated

Sh
I miscarried on March 12th, and it was completely different to my previous miscarriages. I only had medium type bleeding and it only lasted a week with no whole sac coming out this time (sorry tmi!) 
Anyway, I had my 1st period on 20th Apr which was normal but then a couple days ago I had 2 days of really light brown discharge in my knickers even though I wasn't due on for another 12-15 days. Has anyone else experienced this? I know your body is all over the place after miscarriages but it just seems weird to me ...
If anyone else has been through similar or has any opinions I would really appreciate advice. Thanks so much in advance
