Hi all! I have been on the pill for a week and 1 day. I am almost 30 years old and never been on it before. I have a ridiculously irregular period every 16-24 days. I am feeling so irritable since taking it. I am being strong to talk myself out of the moodiness but I feel like I may lose it soon. I am also having some break through bleeding which I heard is normal. Anything advice or support is greatly welcome! :-)
