Is sex every other day with preseed still effective?

I find tracking so stressful and I always throw myself completely into it and almost all of my thoughts become about tracking. I’ve got an 8 month old so I don’t need my mind consumed with tracking. I’ve got a rough idea of how long my cycles will be. Is it just as effective to ttc every other day using preseed? Or do I need to make myself crazy with tracking ovulation? 😅

I mean sometimes it’s like this (well most of the time) x x xx x xx

X’s are sex spaces in between them are the days between.
