please answer as soon as possible, me and my boyfriend are very stressed & want our minds at ease.
Well, that's within the fertile window. If you had unprotected sex on day 9 or 10 of your cycle, and you're young and healthy, that's within the fertile window where you can get pregnant. Wait until your period is due and take a pregnancy test. The fact that he didn't ejaculate is on your side - it's less likely you'll get pregnant than if he finished.
