When my husband and I were planning, my mother gently told me to focus on my health and tracking my cycle naturally. Doing it around the 10th to 16th day of your cycle, every alternate day, is usually the best window.
Having relations every 2-3 days throughout the cycle, especially around day 12 to day 16, worked naturally for us. Just don't stress, but if you have irregular periods or any pain, it's always best to consult your gynac once.
Tracking ovulation with simple test kits is great, but also keep your diet healthy and low-sugar to support your body's fertility. We made sure to try every alternate day during my peak fertile window.
For us, using an ovulation tracking app was a game changer. We tried during the fertile window shown on the app, especially the 3 days leading up to ovulation, and that's how I conceived.
When we were trying, I felt so much pressure to get the timing perfect. We tracked my ovulation and did it during my peak fertile days, which was usually 12 to 14 days after my period started, and it worked!
