I was having a really awful time with Yasmine and having extremely long periods. So my Dr. switched me to a different pill and that didn't work, and then he put me on Femcon. Well I've been on it for about four months for the past three I've had a regular period, but right now I still have a week left on my pills and I'm spotting, and have had horrible stomach cramps for the past two days. My Dr. says I should keep on the pill at least for a couple more months.
