Pregnant?: Yes, "pre cum" does contain sperm. Therefore, you could become pregnant. Best to use some form of contraception, as the withdrawal method is not effective at preventing pregnancy.

It's possible.: if you were at your fertile portion of your cycle, it is certainly possible. If you miss your upcoming period, perform a home pregnancy test. Good luck.

Yes: Each drop of pre-cum has millions of sperm in it. So pre-cum can get you pregnant anytime you have intercourse. The day before your period is not the highest-risk day but you should assume that anytime you have unprotected intercourse you can get pregnant? Why not use birth control? Best wishes!

Possible: Pre-cum is known to have resulted in pregnancy. If you miss your period by more than 5 days, do a home pregnancy test. if it is negative, repeat the test in 3-4 days, use first morning urine and follow the instructions carefully. You could see your doctor for a blood test the day after a missed period. It would be positive if you are pregnant. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine.

Unlikely if your: timing is correct about your period. However, never say never regarding pregnancy. Use protection every time if you are not ready to become pregnant.
