month 3 TTC

Month 3 of ttc. Trying to just go off my period apps and TTC apps this month. Testing gets too stressful. The past 2 months I have been too tired or fallen asleep on my ovulation day so that could be part of it, but how often should I be haveing sex? Every day, every other, everyday during fertile time. I did get pre seed this month. Period ended Sunday. Ready for my rainbow baby
