I don't know about the coil, but have heard people refer to it on here, what exactly is it? If it excreets any kind of hormones like the pills do, it may take awhile for those to get out of your system first but anything is possible, I know people who have gotten pregnant while taking the pill too. I'm ttc baby#2 too, my daughter turned 2 on August 9/04. Have you started your prenatal vitamins? Start getting your body ready by taking folic acid?vitamins, eating and sleeping well, and abstaining from drugs/medications, alcohol and caffeine(or at least limiting caffeine). Goodluck
