okay so me and my boyfriend.. had sex and the condom broke. This was my first time having sex and he did not ejactulate and it was eleven days after my period. I took plan b 12 hours after.. and a week later i got spotting. im really scared.. i took a pregnancy test twice but i think it may have been too early to tell. they both came out negative. However, i've missed my period..its already 5 days late now. im really stressing and i dont understand why its not coming! What oculd be wrong with me? and should i get it checked out?
