<s>[INST] hi there, i had the depo injection in august and again in october (i think!) and continued having periods. now that it should be out of my system i havent had one. i am trying for a baby and want to know if there is a way of finding out if its still in my system. also how common is it to stay in a womans system for longer than the 3months its supossed to? Thanks nic [/INST] After the injection in October, its effect stays for 3 months so it will go on till jan. the bleeding after the injectuin is not a period , it is break thru bleeding due to hormone imbalance caused by the injection. </s>
