So, I’m considering having my ParaGard IUD removed on monday. However, I’ve had unprotected sex on Thursday. I am aware that the sperm can survive inside the body for up to a week, but does anyone know how long it takes for the copper to kill the sperm? I am also on the pill, but have just switched to a new brand, and I am only 4 pills in. I’m scared that I might fall pregnant after my IUD is taken out. Any advice? Many thanks!
