Yes, it is possible. Ovulation is the day the egg is released on its "journey" from the ovary into the fallopian tubes, traveling to the uterus. It is possible for sperm to fertilize an egg in the fallopian tube.. The fertilized egg then continues its journey even afterward, and eventually will embed in the uterus under normal circumstances.
The day of ovulation differs in every woman and it is very hard to find out exactly the day you start ovulating. There are many ways you can find this out. If you know the exact day you ovulate then this is great. During the time of ovulation an egg is able to be fertilised for about 12-24 hrs. However sperm can live inside your body for up to 3-5 days and the egg is available for one day. It is said that you are most fertile around 5-7 days. Try every day if you like. More tries the more chances. Good luck with conceiving!
