Hi I am 15 and I am on birth control. I have a couple of questions. I have been taking Aurovela Fe for a couple months now and its made me gain weight and feel super weird sometimes. I cannot find my birth control pill pack and I think I left it at school. I take my pill at 4:00. I have another type of birth control from a while back that I hated because it was really strong. Its called Estarylla and I decided to take that because I don't want to have my period or fully miss this pill. Will I have my period because I switched birth control? Is it safe to switch to Estarylla as the same time every day instead of the other birth control? Do you think my body will be more used to the Estarylla now that I've been on another type of birth control for a while? Before I got extremely tired after a couple of hours of taking it and I was dizzy every day and could barely stand up or walk straight and felt nauseous. What type of methods can I use to not be gaining all of this weight and will it go away? Thanks
