I have been taking LoE24 since February 11th. At first my period was light and mild cramping. This month I had spotting for 2 days around the 13th, and then again on the 15th. Now it is the 29th and I started bleeding on the 25th and it is really heavy. Has this happened to any of you? Is this normal? I think I have gained weight and I have back pain, and mood swings. Every once and a while I have pain under my ribs and on my side as if I have just ran 3 miles. What should I do?
