"I have had several experiences with BC, this is by far the WORST pill I have ever taken.  I have an eight month old, was put on this pill because I was breastfeeding.  I had cramping so bad that my DR ordered an emergency CT scan because he thought my appendix was going.  I could literally freak out at the drop of a hat, and cry just as a quickly and for no reason at all.  DR thought it was postpartum depression, turns out it was just this crazy pill.  Days after stopping this terrible medication I feel like I have gotten my life back.  Mood is better, no anxiety, I can sleep!  And the pain is going away."
