    I am 30 years old, I haven't had a period in 3 months. I took two blood work and pregnanct test and they all came back negative. When i went to the doctor I had found out that I had a UTI. Can that stop my period from coming down. I am so confused because nobody can not find anything wrong.

    Dear An: No, a UTI is not a common cause for missed periods. The most common reason for a menstrual pattern like you have described is not having an ovulation every month. In a normal cycle, estrogen is produced all month. Estrogen is responsible for building up the lining of your uterus so you have something to shed each month. The good news is that you have enough estrogen to make a lining that does shed usually.

    In a normal cycle, progesterone production increases following ovulation and release of an egg.. Progesterone "stabilizes" the uterine lining in preparation for a possible implantation of a new pregnancy. If you are not pregnant that month the levels of estrogen and progesterone fall, triggering the release of the uterine lining—your period.

    So, if you do not ovulate, the estrogen build up of the lining continues, but without the usual ovulation associated progesterone. Thus, the hormone levels don't decline, and the lining stays up inside the uterus—your missed period. Alternatively, the built up lining can begin to shed on its own creating erratic bleeding patterns which are usually "too-light" or super heavy and prolonged.

    There can be MANY causes for not ovulating: low thyroid, pituitary problems, ovarian cysts, physical stressors (eg sudden increases in exercise, crash dieting), emotional stressors (problems with partners, boyfriends/girlfriends,money ), increased body weight, anorexia, rotating shifts at work, etc.

    Most all of us have missed ovulations through out our lives. If you have been several months without a period, a gynecologist may give you some progesterone in a pill form (eg Provera 10 mg for 5 days). Within 48-72 hours after stopping the progesterone your "progesterone blood level" will fall, triggering the release of the lining that has been building up. Many women report that these periods are very heavy-- as though several months of lining are shed.

    Hopefully your own "natural" cycle will reset itself. If it does not you should see your GYN or local family planning clinic. They can prescribe generic Provera pills to induce a shed of any built up lining and begin a basic work up to see if missed ovulations are the cause of your absent flows.

    Yours,
    Jane
