My doctor prescribed me Alexa in continuous use ...

Hi Dr. My doctor prescribed the Alexa in a continuous use, I am already at the end of the third card, but my period came this month and with strong cramps. I'm worried and I do not know if I should keep taking the medicine anyway. Would you help me? Thank you!
Expert answer:

You should continue as your doctor advises and as soon as possible return to her to decide what to do. Such bleeding may occur eventually when contraceptive is taken continuously.
