All about Injectable Contraceptives

So i got my 1st shot this august 3. The brand they injected in me is lyndavel. Anyone here too decided to have an IC? In 19 years old and a mom :) i have a 2 year old baby girl that i gave birth through Cesarian Section so i want my next baby until shes 4 or 5 years old. Im using FAM lately but this last month my period got delayed that makes me so being paranoid haha im panicking an nervous for the whole month!! So i decided to switch to IC shots.
