I’m 17 years old but just after I have my son I will be 18 years old, my fiancé already has 2 kids of his own and ours will make 3, and my first, Ive been really thinking about getting the birth control needle or the IUD, but I’ve also considered getting my tubes clamped so that way when I’m ready for another child I can have them unclamped. Just wondering what’s the best birth control, I can’t remember to take the pill everyday even if I set a reminder, I switched to the patch last July and by September I was pregnant. I just don’t want the same thing to happen and I end up pregnant right after I have my son🤞🏻 I love kids but it will be way to soon and quick to have 4 children.
