RockRose has it. Those sperm are determined! They can live several days waiting for you to ovulate.
I can't tell specifically what you're talking about, India, and specifically what it is you're asking, but the answer is probably yes to the question you are asking.
As Kay said, you have to ovulate to be pregnant. But it can be hard to predict when you're ovulating, and healthy sperm can live quite awhile.
So having sex with a very fertile man up to 7 days before you ovulate can result in pregnancy. You don't have to have sex on the exact day you ovulate to get pregnant.
I'm not 100 percent sure but I don't think it is possible because my doctor told me I must ovulate to get pregnant and he sent me to buy the ovulation kit to be sure when and if I was ovulating
