hiya i am 22 years of age and feel extremly daft having to do this!!1 i have had the implanon implant for nearly 3 years now!! my periods have always been irregular so could use a little advice. i recently had unprotected sex about 3 weeks ago!! i had a light period after this which only lasted about 1 day! over the past week or so i have been extremly tired and feelings of sickness and dizzyness throughout the day i. am urinating more frequently, and cannot drink coffee which i used to drink by the bucket! i have also gone off smoking and have a strange taste in my mouth!! i know its a little strange to think i may be pregnant as i have the implant but i have been pregnant once before which sadly resulted in miscarriage and i cant help believe that i am pregnant!! i think?????
