Spotting?

Hi I’m 20 years old and had a miscarriage October 12th 😔 of 2018 and ever since my periods have been different, last month my period lasted longer then usually (6-7 days) it went on for 10 days. At the time didn’t think much of it since my body is still recovering, that was my excuse but now this month I ended up getting my period 2 days earlier and it ended (at least I think it did..) on the first of this month but I’ve been experiencing what I guess I should call spotting from the 3rd-5th of this month (March) is this normal? Is it because my body is recovering from my miscarriage? Should I be concerned??

Please leave comments letting me know what you think might be the cause and if I should see my obgyn?

Thanks
