Help me figure out my cycle - so confusing

Could someone help me - I’m not sure I actually ovulate because now the strips are all over the place. I haven’t gotten the egg white CM and I usually get it every month. Last month was two weeks late which made my period two weeks Late. This month According to the app my period is in 5 days. I haven’t been using the numbers given with the strips because sometimes the line was darker than another time with a lower number. I’m not sure. What do you guys think? Keep testing?
