no period after taking provera

Hello, I have been taking provera for two years to get my monthly period. I have PCOS and my dr offered me provera instead of birth control because I smoke cigs. I normally get my period everytime I take provera within 2-4 days of completing the provera after taking my monthly dosage of 10 mg for 10 days. This month, I took my provera, and its 17 days days later and still no period. My dr had me get blood test done to check progesterone levels, hcg levels, and a eco(cant remember the exact name) and a pregnancy test. I did have unprotected sex on Sept 21. Is there anyway possible that I am pregnant.

Hi!
That is the one draw back to taking provera instead of birth control pills--it doesn't prevent pregnancy.  It is quite possible that you are pregnant--in fact that is the most common reason for amenorrhea (no period).  It is also possible that for some reason the lining of the uterus didn't build up this month so there was nothing to slough off at the end of the cycle.  It sounds like your doctor did the correct tests.  IF you are not pregnant, you may want to check an FSH and estradiol level as well as thyroid and prolactin levels.  If you ARE pregnant you don't need all this blood work.
Good luck!

My situation is the same as the person who  has been regularly taking Provera.  My gyno started me on Provera (10mg) for 10 days in April and then Clomid 50mg to follow on day 4 of my period.  Well end of September (my last period) I started taking taking Clomid 100mg on day 5 of period.  On day 29 after my last period -- took a preg test it was negative -- started Provera as I usually do for 10 days.  It is now 15 days after completing my Provera cycle.  dr said it was Took a preg test yesterday  -- was negative, but didn't have a good urination (clear water looking).  So I am waiting 3 days and take another and then I will call the gyno back again.  What is going on?
