You wont know a day after you have sex. You will have to wait a few weeks until you can take a pregnancy test. Next time make sure you use protection! That way you dont have to worry about getting pregnant or catching an STD! Good luck and God Bless!

hey, you wouldnt know the day after you had intercourse. in a few weeks id recamend taking a pregnancy test. but hopefully you get what you want in this hole thing. and there is birtch control and condoms sweetie.

Do you have any advice on what to do if your cousin dies in a really big car wreck??? PLEASE HELP ME

if your periods are regular, (28 day cycles) you will usually ovulate 14 days after, so you could be at your most fertile. go to the health department and get plan b, its free and will end a conception at the beginning. Otherwise you need to wait till your next "missed" period or around March 25th to take a pregnancy test.

you can get an ovulation kit to test when you're ovulating (when you're most fertile) at the drugstore. usually it's two days in the middle of your 28 day cycle. (so around day 14 and 15 ish). go get the kit and it willtell you!

you could use charts on the net to find out when you ovulate
