Are any of you on birth control? What are you using?

I was looking into Kyleena. I was pretty set on it. But then I saw that breastfeeding can increase the risk of the IUD embedding in the uterus and it deterred me from it. I’m not even having sex right now but in case I do, I need birth control. I cannot be getting pregnant again anytime soon. I’m afraid if I take the pill or something, I’ll be careless with it since it since I’m not having sex and then when the opportunity arises, I’ll have not been taking it properly. Just wondering what others are doing. I haven’t had my period yet so <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> would be daunting. I’d have to test every single day and I don’t want that.
