After I had my daughter I bleed for about 3 weeks I stopped and havent bleed at all since my daughter will be 2 month on sept 22 2015 I got nexplanon sept 8th and its sept 14 an accident happened now I'm freaking out my doc. Said wait 2 weeks to be safe should I be freaking out this bad or does it take effect fast I read some places that if your on your period and have it put in while your on it your safe for sure
