Is the cervical cancer vaccine causing any delay?

User Profile
Hi Doctor(s),
My wife had had the 3rd shot of Cervical Cancer Vaccine on 5th July and she has not gotten her periods which was due on 8th July, 2012.
[LMP is 11th June,2012]. She usually has her periods on time in 28 days.
Is the vaccine causing any delay? We are confused, please reply at your earliest.

Hello Raj,
Welcome to ehealthforum,
If she is not on any birth control measures, and if you have been sexually active without protection, the delayed periods could suggest pregnancy possibility. Variation of 5-10 days n menstrual cycle length is considered to be normal and delay could be due to the vaccine. Look out for development of any new symptoms if pregnancy is suspected. She should visit her gynecologist for further evaluation and assistance if she does not get her periods within 10 days of expected period dates, or gets abnormal bleeding. If pregnancy gets ruled out and if you are not ready for pregnancy, but intend to remain sexually active, you should consider getting her started on suitable regular birth control measures to be protected (after her periods). She should be regular with birth control use as instructed. Avoid having unprotected sexual contact if you are not ready for pregnancy.
Take care.
