I don't have regular sex with my boyfriend but we did have sex a couple of days after or before... I cnt quite remember... well anywya I'm just scared now because I finished my pack on tues... with today being Friday and still no period... wat the liklihood of me being pregnant? I only missed 1 n the rest I took without fail... but I'm still scared... please help... thanks xxxx
