"At first I just experienced stomach troubles occasionally with this pill. On the plus side it made my period much lighter but it has been inconsistent. I usually have a 25-day cycle. I have been 10 days late and 5 days early on this pill. Then the 10 pounds came on, and quite quickly. I&#039;m 44 and have been the same weight for 20 years so it was upsetting to have clothes suddenly fit very tightly. I haven&#039;t changed my diet or exercise regime so I attribute the gain to this pill. I feel bloated most of the time too. Other than that I didn&#039;t experience the other side effects some are experiencing. "
