I'm 2 weeks delayed (my last period was on January 27, i think it was irregular bcos my last last period was on December 13 and it should be on January 13 but it came late) i had sex with my boyfriend a lot on February and March 8 and today (march 13) this day, we had sex 2 times. Im worried, am i pregnant? Or does sex causes delayed period? btw, we're not using condom, but he always pull out and ejaculates. I need answers, asap. Thanks!!
