I lost my virginity a few weeks ago and now my period is a few days late? i used a condom, pill, and plan b since he fell out after he pulled out.

Prob not: If you used a condom correctly, and you're on the pill and you took plan b, the chance if you being pregnant is about (.15)x(.15)x(.15)=0.003 or 0.3 %. Now i'm not saying it's impossible, but very very unlikely. Take preg test to reassure yourself. Find a doc to start a more reliable (less anxiety provoking) long acting birth control. Look up iuds and subdermal implant.
