Period Problem

Kenya

So I was on birth control for 6 years before my husband and I decided it’s time for another baby. I removed the birth control Aug 2018 and I got a period right after, but September, October, November passed and no period, then December came and bam Period!!! We are a little after mid January and no period again. My question is, is this normal ? I mean do you even ovulate it there is no period ? I’m frustrated. Help!!
