Hello everyone. I gave birth three months ago, my second child. I want to put in a coil because I'm afraid of raising it. They have me on a period, this is nonsense. But only when there's no menstruation. They said we only put it in after ?. How do I do it? I breastfeed with my breasts, I raised the second one during lactation.
