Period irregularity

Hello Ladies, I come to you seeking opinions in regards to my cycle’s regularity. Below I have included screenshots of my period over the past 5 years. The period of regularity (consistent 28 day cycle) is when I was on birth control, but for as long as I can remember my period has never been “regular”. I’m going to my gynecologist on Wednesday of next week, and I have been going back and forth with myself on whether or not this is irregular enough for concern. I do not live a stressful life, I have no major health conditions, nor are my periods painful. I’m 5’4 and 147lbs. I’m lean but I have noticed an increase in facial hair and skin tags on my body. I will include a picture of myself just so you can see my body type. I appreciate any insight.
