Periods after Ortho Micronor?

I was on Mirena for 3 1/2 years and went on the pill about 2-3 weeks after having it taken out. After a month of being on the pill, I switched to Ortho Micronor. I was on Micronor for about three months but stopped taking it because it gave me migraines everyday that wouldn't go away.

While I was on Micronor, my periods stopped altogether, not even spotting. I've been off of it since January and have only gotten spotting when my period was due. I was just wondering if I'm going to start getting "normal" periods again and if it's normal that my periods have only been spotting for the last six months since getting off Ortho Micronor?
