In brief: Not the Right ?

Successful pregnancies happen frequently with pre-ejaculation.
It is not possible to absolutely prevent pregnancy from any form of birth control. Some try to do so by withdrawal as may in fact be the case for you, but, this is often without success. Emergency contraception is less successful after 4 days. Consider the new "ella" today if concerned and be more conscientious in the future.

In brief: Risk

Pre-ejaculate may contain large amounts of viable sperm (less common), smaller amounts of sperm that are dead or alive or no sperm. Thus, there is potential for pregnancy with pre-ejaculate.
Sperm need to be deposited in the vagina or at the introitus for pregnancy to occur. Sperm die as soon as they are dry & for around 5 days in a moist, warm environment.
