I'm 25, on birth control for the first time and I am just finishi...

I'm 25, on birth control for the first time and I am just finishing up my first month on Loestrin Fe (I was on Yaz for one month before that). I am a bit concerned that I'm set to start a new pack tomorrow and have not had a period, not even spotting. I haven't really had any of the side effects some are describing of weight gain, chest pain, or hair loss. Maybe a bit more acne than usual, but I had expected that since this is only my second month on The Pill. However reading your experiences I'm beginning to wonder about the mood swings. I have been EXTREMELY pissed off this month, anxious, and stressed, and in general a horrible person to be around. It's like I'm 15 again going through "that stage." It's awful, and I'm quite embarrassed by my childish behavior though I can't seem to help it. I've attributed it to other factors (which, who knows?) but reading your experiences makes me wonder if this pill isn't contributing. I'm definitely going to pay attention; if this continues for another month I'm going to change to another pill. Ugh. I'm also wondering if I'm going to get my period back? I began taking birth control to control my normally heavy bleeding and severe cramps. Not to eliminate my period entirely!
