Conception takes place as soon as the sperm and egg - or ova if you really wanna be technical - meet. But - sperm can live inside a womans body from 5-7 days. So within a week of sex. The other thing is once the egg is released it must be fertilized by the sperm within 24 hours. So if u know when u ovulate that can really help ... I sound like a pdr teacher hope it helped ~melissa

So if I ovulated on the 8th of august and I had sex that day it is possible for me to have gotten pregnant that same day?

Hello you could definetely get prenant if you ovulate aug 8 and have
sex that day you are most fertile on the day you ovulate and the days
that lead up to that day good luck to you
