I was on Yasmin for a month and bled for a month straight. I absolutely hated it! I felt really irritated by everything and just felt overall terrible. My doctor switched me to Ovcon, and I decided I was going to go back off the pill all together. I was having really, really having bleeding, so decided to get on the Ovcon 35. The first month was rough. I take it with dinner, so it was a little tough for the first few days due to nausea. Once I got passed that, I had some breakthru bleeding, but generally felt okay. I would notice that I would feel like I needed it about my last hour of work. The second month, I had very mild stomach upset the second day, but was good after that. It hasn't helped much with PMS, but has made a huge difference with my bleeding. So far, I cannot complain as compared to the Yasmin.
