"People who are giving this a bad review either aren't letting it get into their system or are some of the few that will suffer from the side effects that come along with taking any medication.  People who write a bad review saying they have only been on it for 6 weeks or a couple months have not let their body adjust to a new pill.  I have been on this pill for 6 months now and have no real complaints.  In the beginning I spotted here and there and my period lasted longer than 4 days.  It is better than bleeding for 6-7 days. Give it a chance."
