About a month ago I lost my virginity. Since then we've had sex like 5-6 times and hes never worn a condom. (I tried to tell him to but I caved once. Held strong since then tho). He pulled out and came each time, but I am now 3 days late for my period. I had a normal period after the first time but theyve never really been very regular. Im scared. Should I take a pregnancy test? The last time we had sex was about a week ago.
