Chart Help PLEASE

Has anyone ever had a chart like this? It originally had me ovulating on cycle day 14, Which is pretty normal for me. Then I had this weird zigzag pattern and no progesterone surge, at least by temperature, and now it has me ovulating on cycle day 23 instead. My husband and I don't use birth control outside of my fertile window, and I was sure that I had ovulated before. If this is right, then I had sex in some of the best times to get pregnant? Unprotected sex. Please no comments about our birth control methods. Hormonal is awful on me, and we decided that we would rather take the risks of getting pregnant. It's not the end of the world if we do get pregnant, but this is definitely unexpected. I was originally supposed to start my period tomorrow, but now Glow has pushed back that estimate. My cycles are usually between 30 and 34 days, and I've not had one greater than 35 in a very long time. I'm 21. Has anyone ever had a chart that looked like this? If so, do you have any ideas as to an explanation? I'm so confused!
