Ok, so me and my boyfriend had sex on march 2 and according to an ovulation calender i cross referenced today that was one of my fertile days. (my first day of my last period was on the 20 of feb). So I started to get sick, thinking it was the flu, then my boyfriend got worried thinking i was pregnant. Although we were careful we had started to have unprotected sex then put a condom and finished. Is there anyway i could be pregnant? like from pre-ejaculation or what not? I took a test but im worried it was too early. Any answers would be appreciated.
