I started taking this in an attempt to regulate my cycles, which have been very irregular for years. I only took it for about three months before getting married (and at that point, I was not expecting to be married any time soon). My cycles went from an average of 57 days (with an occasional over 70 days; I probably have PCOS), to 30 and 40 days. I was hoping for regular 30-day cycles, but even 40 days is much better for me, so I was not concerned. I consider Positively Pregnant to have worked! After getting married, I kept taking it to continue regulating my cycles. I've been married about 4 months, and I am at least a month pregnant. Given my wild cycles, I was not expecting to get pregnant so easily/quickly, and I was dreading the possibility of fertility treatments. I'm very thankful that my husband and I will, Lord willing, have our first child in our arms next summer! I do believe that Positively Pregnant is a part of why this is so. Thanks for a great product that has worked so well for me. Psalm 127.
