avoiding pregnancy

what is the safest time to have sev to avoid pregnancy

Well, unless you're happily married with a moderate income, I would venture to say-Never! Sex (which can always lead to pregnancy) is not something that should be gambled with or something to be outsmarted.

And unless you are ready to deal with being responsible for someone else for at least the next 18 years, I would suggest that you try other ways to have fun. So many people will tell you that sex isnt a big thing but being pregnant before you're ready (and I dont think anyone is totally prepared) is something that will change your life FOREVER. Doesnt mean it will ruin your life but having a child is all about sacrifices. And one sacrifice you can make for your (in the distant) future child, is waiting until you are emotionally. financially and mentally prepared to bring another life into this world. I dont mean to sound harsh but hindsight is always 20/20.
