I was on Ortho Lo and I was very moody and down a lot. I always got ticked off for no reason or stupid little things. I have recently switched to Lo Ovral, a monophasic pill, and things are MUCH better. I am so much happier on it =)
You should try a monophasic pill where the hormone dosages are the same throughout the month. My problem was, that on Ortho Lo, the dosages would switch each week and it just drove my body and mind crazy. Best of luck-Sunkissed
