Risk of Pregnancy

Can I get pregnant if I have unprotected sex but the man does not ejaculate (cum)?

It’s probably very unlikely that you will get pregnant, but
you can’t know for certain. Three
small studies found no motile sperm (sperm capable of reaching/fertilizing
an egg) in the fluid in a man’s penis before he ejaculates.
However, a more recent study found that 41% of subjects produced pre-ejaculatory samples that contained spermatozoa and in 37% a reasonable proportion of the sperm were motile.

So there’s no harm in using emergency
contraceptive pills (also called "morning
after pills" or "day after pills") to put your
mind at ease if you are not sure if your partner ejaculated or you
are worried because you had sex without using contraception or your
birth control failed. Remember that emergency
contraception can’t protect you against sexually transmitted
infections, like HIV, which has been found in pre-ejaculatory fluid.
If there is even the slightest chance that you might be at risk for
sexually transmitted infections, be sure to use a condom.
