Missing period?

I'm 21 years old and I had my daughter in October 2019 and a few weeks after having her I had a week long period followed by spotting every few weeks and now absolutely nothing. I breastfeed as well as pump, but I figured that when I started my period I would get them regularly again. I am on Norlyda, but I also figured that with the way I miss my pills often (ADHD causes me to forget often even with an alarm and I'm trying to get on schedule better) that I should be getting a period where I'm not taking them exactly on time or missing one a week.
