Symptoms of pregnant: Any or all of the symptoms you describe have been described by other women who are pregnant. It would certainly be worth your while to get a pregnancy test.

Pregnancy possible: Pregnancy is always on the list of possibilities when a woman has abnormal uterine bleeding or cycles. You may be having anovulatory cycles (cycle without producing an egg from the ovary). If a urine pregnancy test is negative, i would recommend evaluation by your gynecologist, and treatment will depend on the cause of the abnormal bleeding and your current short-term pregnancy goals.
