Welcome to HealthcareMagic, Your are correct on the fact that pre cum fluid can also result in pregnancy as it may contain sperms. There is a small chance that you may be pregnant. My advice to you is to wait for 20 days from the date you had sex and then repeat a urine pregnancy test. Then it will give you an accurate result about your pregnancy status. If you get your periods before that, it means that you are not pregnant. Hope that answers your question, Regards, Dr.Imaad.
