I just got blood work done and have been told i am very anemic. I am 20 years old, a female, 5'5 and 117 weight. I am taking adderall instant release 20 mg once a day for adhd and i have the implanon birth control implant. I have been feeling extremely fatigued and its caused my sleeping schedule to be all over the charts. I mostly sleep during the day and have no energy for physical activities. My menstrual periods have been lasting up to 4-5 weeks. Could my adhd medication be causing this? or could it be the implanon? I'm just trying to find the source of the problem and what to do about fixing it.
