Hi I'm 27yrs old, 5ft 7" and 162lbs. Back in Febuary I thought I was pregnant because I missed my period, so I took several HPT and they came back negative. I waited a couple more weeks they took another HPT and they were negative so then I went to the GYN n took a test and it was negative. Back in Febuary I had this terrible pain in my left side and it was so bad that I went to the ER and they found nothing wrong and just gave me pain meds. Since then I have had stomach pains, constant back pain and from time to time a experienced sharpe stabbing pains between my back n left side. I've also gained weight, been extremely tired even while taking vitamins. I have on and off headache, nassea and increased and decreased appetite. The most obvious thing is my disappeared waist line and bloated stomach. I've also had palputations in my stomach and feel movements in my stomach. I haven't had a real period since my last on january 6th but have only had light spotting around the date of my expected period. I have read every biology and human body book possible rying to diagnose myself. I have no idea what is going on with my body for the past 7-8 months. Before January I haven't had any medical conditions, well nothing serious. Any advise will be greatly appreciated as I'm out of options..
