Their's always a chance of pregnancy when semen ejaculates in the vagina. Typically its 12-14dys after your 1st period your most likely for pregnancy. When in doubt take a test, only assured, eas minded & stress free way to find out. If you stress to much it raises your chances of delaying your period in turn causing you to stress even more. Take a test once & for all.
You usually start to ovulate 10-12 days before your period starts, a sperm can live upto 7 days in a womens body i believe. This doesn't mean you are pregnant though. Hope this may help.
