hi, i'm worried about being pregnant....last month, i missed two pills (NOT in a row)...i took them the day after once i remembered and my regular dose for that day as well (i'm not sure one which weeks i missed them) then, on the 4th week (the placebo week) i got my period...it was normal...then i started a new pack on sunday of this current month...that same sunday night i had intercourse...what are my chances of being pregnant? i have always taken my pills on time since then...
