I am sexually active and i have irregular period. i missed my periods so i took deviry but still haven't got my periods even after 10 days from intaje of last pill. what should i do doctor? and can i take deviry again and when?

"Deviry" is a form of progesterone. If taken and no bleeding occurs after "10 days" from stopping Deviry, it is possible that pregnancy has occurred. Obtain a serum HCG test to be certain about pregnancy. With "irregular periods", and ovulation has occurred late in this cycle, there will be no bleeding, and the HCG test will be negative. Ask your gyn about birth control pills.
