Cycle after miscarried ! Confused!

I had a miscarriage on December 30, 2014. It was medicated because of a blighted ovum. My first period was February 7, 2015 and I bled for 5 days and Then spotted for a week. I got my period March 13, 2015 and it went for 3 days lighter than normal and no spotting after. Before my miscarriage my period was 4-5 days with a few days of spotting. So do you think my February "period" wasn't a period it was just residual bleeding from miscarriage ?
