I had some trouble during the first pack -- no nausea or anything, but after about 6 weeks I had BAD mood swings...crying, irritation, anxiety. Once I realized it was the Seasonique I was able to better control it. Also, there was some spotting after sex occasionally.

When I had my first period it lasted about 6 days, no heavier than when I was on Demulen. Cramps were a little bit longer-lasting...three days instead of two.

Second pack I have had NO problems (except for a little breast tenderness), and I love it! Make sure you take it at the same time every day.

Now my only complaint is that I get paranoid and think I'm knocked up! ;)
