With the norplant, is it probably best to wait until the rod is removed so that your cycles can get regular again. My cousin has taken antibiotics, and any other kind of medicine to decrease the effectiveness of this implant, and it did not work. I just say wait until you get it taken out, let your cycles get normal, and then start trying. I know it's hard to be patient, you feel like you biological clock is ticking, but it's not. It will happen when it is time. You should focus on school and enjoy your fiance. Trust me, I had my firstborn son at 20 years old, it's not all it is cracked out to be. Sure his father is in the military and pays child support, but he does not see him, does not want to see him, and he can be next door with his daughter, I have little to no time for myself or things I want to do, and I was prepared for this baby. When this child comes into the picture you want to have accomplished some of your goals. That way you can tell your baby, I did this, I traveled there, maybe one day we will take you. And you never know what the pregnancy is going to throw your way, you could be crippled with morning sickness, putting you behind in your classes, or you could have a complicated delivery. You should at least consider ALL pros and cons of the situation before jumping into it. But I am proud that you are in nursing school and doing well for yourself. Not a lot of teens can say that. You go girl. Just do me a favor and really think about it.
