According to my ovulation calendar, i was fertile the 9, 10, 11, 12 and tomorrow would be my most fertile day. if i unprotected sex each one of those days and once twice, what are my chances of getting pregnant? also, would i be feeling sick so soon?

About 25%: A couple only has about a 25% chance of conceiving any given month. Any sick feeling you are experiencing is not related to possible conception. It takes a few weeks for hormone levels to rise to the point that is high enough to cause suck feelings. Good luck!

Roughly 20% if...: At 18 years of age if you have no fertility problems, and if the male partner is also entirely normal, the per-cycle chance of conception is roughly 20% - no matter how hard you try. No, you will not have any reliable pregnancy symptoms this early.
