Ovulation

Here’s kind of an obvious question: Let’s say you have irregular periods, and usually my cycle is around 50-60 days. Usually you ovulate 10 to 14 days BEFORE your next period. Now here’s the question: if I have sex WEEKS before I actually ovulate because remember, I ovulate almost a whole month later, I can’t get pregnant, right? Since sperm can only live a maximum of five, up to SEVEN days if in perfect moist conditions, it shouldn’t be possible, right? I know that sometimes ovulation can happen earlier too, and that’s where I’m kind of concerned. Can y’all look into my last post for more info? Or is that not possible?
