"i was put on natazia by my ob about a month ago to stop the growth of my ovarian cyst, heavy periods, &amp; cramping. i did notice i was a bit moody, but it shrank one cyst to half it size. i lost 10lbs in the first month. it lightened my cycle the first four days, but it&#039;s day 10 with no end in sight. i decided to stay on it for my cyst though."
