Hello and Thanks in advance for your response... I am a 21 year old, and have been late for my period for 10 days now. Thats irregular for me,when I am late its usually for 2-4 days,never more. Im under decent ammounts of stress lately, I cant sleep at night, up till 5 AM at times and wake up at 1-2 PM then come 7 PM I sleep for a bit. I have cramping as usual and back/chest pains.Breats are sore, headaches now and then,and irregular heart beats(fast) for a few seconds.Also something that usually happens to me I dont know why, I get these unusual brusings around my body. Happens alot,around the time of my period or not, it happens. I went to the doctors for this, and she said it was normal. But told me to take vitamins,which made it worse I think, because my hair started to get thinner! and still is getting thinner when even though I stopped taking them. FOOD!! something I THOUGHT I LOVED! but now i cant stand eating anymore,when I do, i just never finish my plate, my apetite is just not there anymore. Im 4'11 and weigh 115-118 thats normal for me. ANY RESPONSE please..
