Ovulated cycle day 10!????

Trace • I have a 18 y.o. Boy. 13 y.o. Girl. Ttc since 2015. Miscarried Mar 2016/May 2018/Oct 2019/Apr 2020/Apr 2021/Nov 2021/Aug 2022/Dec 2022/May 2023. Ttc our 🌈 baby.
Ok my usual update but have came across something. I noticed that my cycle day 10 is my darkest and strongest!!!! Did I ovulate then??? I've been taking them at the same time each time. 🤔
