Where and when does fertilisation happen?

Well when your ovualte you release an egg. Then the egg hangs out in the falopian tube and waits for sperm. If sperm does come and fertilize the egg then the egg travels from the falopian tubes and to the uterus where it will attach itself to the uterine wall. once the egg is released the whole process could take like 6-11 days something like that. It takes the egg a few days to get to the uterus and it takes it even longer to implant.
