I have not takin my birth control for like 5 days now and on the weekend my boyfriend came in me a lot ... could i be pregnant ?

Depends: The time of ovulation determines fertility. Usually ovulation occurs 10-14 days before period. Depending where in your cycle you were when you stopped oc, you may be in the fertile zone. Best now to wait until your period comes in three weeks. If you miss get a home pregnancy test. Meantime use alternative birth control if you don't want to conceive.

Yes!: When you miss birth control pills, you exponentially risk ovulating and getting pregnant! ocps these days are very low dose - when you miss, your body thinks it's time to let the eggs go. With more semen and sperm delivery, that further increases your chances of getting pregnant - more bullets in the gun... Now, start watching for signs of pregnancy and have a home pregnancy test ready.
