You need to better understand your body. No, pregnancy symptoms don't appear the next day.

Here's reliable info from a reliable site - http://www.webmd.com/baby/default.htm

You need to understand pregnancy, sex and more before you start having sex.

There is no "sign" the next day, you will know if you miss your period the next time it is due, or it is very very light and only lasts a couple days.

A week after you miss your period ( if you do) is when you can do a pregnancy test.
