Okay, so here's the deal... today's date is December 16, 2009. I have not had my period since August 30 to about September 6, 2009. && my period was late in August. I am/was on Vyvanse 60mg for Inattentive ADHD and this medication severely decreased my appetite, as well as any other stimulant will, and my weight has severely dropped from the medication. I was about 105lbs and the lowest weight that I've been at since was about 94lbs. I have noticed that I am extremely fatigued, I will "nap" from about 4:30pm-8:30pm, then go home and go back to sleep at about 9:00pm-about 6:00am, waking up for school just as drowsy as if I hadn't slept at all. I have had some vaginal discharge throughout the months, barely any signs of receiving my period, and I have taken pregnancy tests and they've all been negative. I have not taken one in about two months or a month and a half and my mom recently said she is getting really worried that either I have something wrong with my thyroid, I'm depressed, or I'm pregnant. I have been pretty stressed with work, school, relationship ups and downs, and worrying about pregnancy. The Vyvanse that I take also causes me to become severely nauseous right after I take it ( when it's kicking in ) and if I miss a dose, I get severely sick to my stomach to the point that I do not want to do anything, but lay down. I am unsure of what to do. I do not want to go to the doctor/hospital because I am afraid of getting a blood test and then it will show that I have THC in my system, I am 18, just turned 18 and my mom is very strict. I need help, lots of it. Please message me if you can give me accurate advice.
