"i have been on lolo for just over a year now (after i finished breastfeeding my son) and have had no negative side effects. the pill has not caused any weight gain or losses, change in attitude or sex drive. i haven&#039;t had a period in about 4 months now and it is slightly alarming that the pill is changing my cycle so much, but as long as i can still have more children when i am ready and my period comes back once i go off of lolo, i consider this to be an excellent birth control pill!"
