Well ,as cerazette
is a lower strength progesterone
containing pill, it needs to be taken daily at a constant time.As you have missed the pills for so many days, five i guess, i think you have to take a back up method like barrier (condoms ), for the rest of the month.Well, since you are lactating you may have delayed periods normally, but i think if you go for a urine pregnacy test / or a pelvic ultrasound
scan ,6 weeks from now only if your perioids are delayed, you can easily detect a pregnacy at a early stage, which you can terminate by medical methods.First you use a barrier method for rest of this month.
BYE TAKE CARE
