The only side effects I have noticed are moodiness and low iron levels. My mood changes constantly, and a Hallmark commercial is enough to make me cry. I don't feel depressed, and most of the time I am fine. My fiance and I get into arguments all the time over trivial things, and until now, I didn't want to blame it on hormones, but after reading others' posts, I definitely think Yasmin is the cause for it. I never used to be this sensitive over every little thing.
Regarding iron levels: Pre-Yasmin, my iron count was alway high. I regularly give blood, and had never had a problem until recently, and I have been told twice in the last few months that my iron count is too low to donate. I thought that it was because I wasn't getting enough iron-rich foods, and have even taked iron supplements occasionally to help with fatigue (I can't go to late movies anymore b/c I will fall asleep in the theater), but nothing seems to help.
I am getting married in May, and I am afraid if I go off of Yasmin now, it will mess with the regularity of my cycle, and I would rather not be on my period on my wedding day and on my honeymoon. I don't know if it would be better to wait it out (I have been planning on getting off birth control all together once we're married). Any advice?
