What are the chances of getting pregnant if one has unprotected sex the day before ovulation? If said person doesn't drink, smoke, or consume caffeine?

Lizzy_Jane,

Are you trying to conceive? or worried that you might have conceived?

I'm not sure exactly what the percentage chances are that you would have become pregnant. Sperm can live and stay active fore a couple of days after intercourse, or so I've read. It could be possible for you to be pregnant.

Well, I took a test yesterday, 2 days before my period, and it was a light line, but definately there. Thanks! I'm going to retest the morning I miss my period with another First Response.
