I am considering removing my mirena. I have been gaining weights and having recurrent vaginal infections. I was advised to put it then cos I have fibroid and my bleeding was heavy. The last time I checked the size had gone really down. It s been 3yrs now and I don t feel comfortable with my weight gain anymore, despite trying to be more active and healthy eating, and i ve become less active for my children. Could you please explain the natural way of preventing pregnancy as I would prefer that at the moment.
