Regular versus irregular

So i have never been diagnosed with anything currently but having a hard time concieving. Had been on birth control since december 2014 and got it removed june 2018. I get a period once a month that lasts 5 days. My periods are sometimes off but only by a day or two. Sometimes i get it a bit early others a little late but overall fairly consistent. I have been using ovusense and for the past 4 months according to that i have been ovulating just on always on the same day. My question is is my period considered irregular
