"I'm so glad I stumbled onto this site and comments. This pill has been a nightmare. I bleed HEAVY constantly for weeks at a time. I'm now severely anemic and am going through iron (iv) infusions. YES like another commenter I have my period for weeks, last month I was on my period 3 weeks. I'm so tired and frustrated that I'm 38 and considering a hysterectomy. I started this pill 9/28/16. Every time I called about the heavy long periods I was told it takes 2 to 3 months for my body to adjust its now been 6 months and like I said I was on my period 3 weeks last month and just had my 1st of 5 iron infusion treatments. Nightmare.. AVOID THIS PILL :("
