That's possible.: Take a home pregnancy test if you miss your period. Take care.

Pregnancy: Could you become pregnant-yes.If your periods are regular, then the chances of getting pregnant are very high. Sperm can stay up-to 72 hours in the uterus and vagina. The only safe way to check this is to do a urine pregnancy test 10 to 14 days. Early tests can give a false negative. If the pregnancy test is positive then you will need an ultrasound to ensure proper implantation of the embryo
