I'm one Big ball of "nothing works"

So.. predicted ovulation day is today.. I have gotten some positive ovulation tests but.. here is the kicker. I'm on my period. Have been for the past TWO weeks. Ok.. my doc said that she thinks my period is regular but that I'm not ovulating regularly. I was on depo in 2014. I think I got about 5 shots before I stopped it. I had my daughter Feb 2018, got the mirena inserted on April 20th 2018 and had it removed on August 14th 2018 because I bled for four months straight and also because we want our second child. So, since then we've used zero protection. My cycles have always seemed crazy to me. One cycle would be a 25 day cycle, the next would be a 30 day cycle and the one after that would be a 43 day cycle. I guess the meaning for this post is not only to vent because I'm so fed up with it but to also ask for opinions and advice. Do I give up completely.. just stop tracking anything, quit going to a doc and try to stop thinking about it orrr do I keep tracking, going to doc and try my best not to stress??? Here is my ovulation test organization. Bottom one was today's, I took it earlier this afternoon. Not too sure what group to put this in because im talking about my period and about ovulation lol and just normal ttc so general ttc it is. Plz comment with your opinion or advice or both. Thanks
