Interested

hi im on about my tenth day of using D right up until about the 6th day everything was going great. Then i started to get stomach aches (is this normal?) and my period. I have the implanon ( i think thats how its spelt.) and have had it in for awhile now. Im on about my third one and have not gotten my period at all during this time. Could the Duromine be effecting this? Im not really worried im just hoping that it goes away soon.

Thanks
