Having intercourse every 2 to 3 days throughout your cycle is more than enough to ensure good sperm quality and hit the fertile window. No need to stress about doing it daily.
Arey, doing it every single day can actually tire you both out and lower the sperm count. Stick to alternate days during your fertile window, and stay positive!
I know how stressful the constant trying and timing can be, it takes an emotional toll. Just try to support each other and remember that timing matters more than frequency.
