Hi, I have had problems ovulating an I have a small ovarian cyst. My Dr prescribed progesterone to kick start ovulation, which worked last month, according to my basal body temps. However, my period arrived for 2 days and was very light. 5 days on and I am getting increased spasming in my stomach, is this related to the cyst? My bbt has been very erratic for the past 4 days high one day / low the next.
