Last year I had the impladon put in, I stopped getting my period and didn't get cramps or any sign of getting my period I wasn't to worried. Now after almost a year I still haven't had a period but I'm worried that my last sexual partner may have got me pregnant I'm suffering from nuisar and food cravings, I took a test 3 months ago and it was negative and we only had sex once with out a condom after that. What are the chances of me being pregnant? And If I am how do I tell my family? I'm only 16 in April.
