Why only one sperm cell can fertilized an ovum?
Ovum has a layer of zona pellucida around itself. When a sperm enters the ovum, the cortical granules present in the ovum, causes the thickening of the zona pellucida. This prevents the entry of other sperms in the ovum and only one sperm is able to fertilize the egg.
How does the ovum prevent multiple penetrations of sperm cells along it's periphery?
as soon as a single sperm fertilises the ovum a change of composition takes place in ovum's outer layer forming zona pellucida which prevents the penetration of other sperms.

How can you go about getting pregnant?
You can become pregnant about 8 days from having your period. Its a better time to ensure you become pregnant. Also, you should be the one laying down when your partner ejaculates into your vagina to ensure that his sperm is well inside, but if you are on top of him while he does, its less likely to happen as the sperm can flow out of the vagina easier. Try refraning from going to the bathroom as soon as you both have ended intercourse. That way the sperm can properly get inside you.
