i have been on the contraception jab until october 2013.. my periods were regular whilst on it and just after the jab run out my periods stopped completely and i havent come on since. iv been sick quite a few times, had numerous headaches even migraines. iv gained some weight not major but enough and keep getting butterflies in my tummy. iv done about 6 tests all negative so i dont know if it could be pregnancy or not my drs wont do anything unless i present them with a positive test.. any ideas or advice?
