I've just switched to seasonale because I have bad cramps and headaches when i'm on my period, so I thought this was a good choice. I am experiencing extreme moodiness and can cry at the drop of a hat. I don't feel like myself anymore and am getting concerned because others have noticed, my husband included. Although my sex drive has increased, I feel angry or sad a lot of the time. I'm only into week 3, but i'm debating if I should go back to my other pills. I did very well on them, but looked forward to the 4 periods/year thing. I don't know if this is all in my head or if this pill really can do this but i'm trying to decide if I should wait another month or switch back. My husband and I usually get along very well but lately i'm upset about everything! Other than that I haven't noticed other major changes, but then again, i'm just starting. I'd appreciate any advice.
