"i used to have really heavy periods. after being put on lutera i had really short and light periods. it was amazing. i did not notice any other changes. i did not gain weight or have fuller breasts or experience any mood swings. i stopped taking it to get pregnant and didn&#039;t have any trouble. now i am breastfeeding and my doctor put me back on it after the progesterone only pill made me spot. we&#039;ll see how it works out."
