I've noticed over the past few months that sometimes I get very grumpy at the smallest things and I no longer seem to have as much patience as I once did. I've been on Loette now for around 7 months. It seems that when I stop taking the pill during the cycle I am fine, however as soon as I go back on it I get grumpy. I've started my new cycle as of two days ago, could it work that fast in affecting my mood?!
