Hello I am a 25y/o female. I have been feeling sick to my stomach for quite some time now. Well over a month. I've had a headache, every time I eat my stomach hurts, like it's in knots. I drink plenty of water, i also have been losing my appetite and not being able to keep much food down when I can eat. I am NOT pregnant. I've taken many tests. I'm also in current use of the implanon birth control. I have had regular menstrual cycles but the last two months I have been bleeding. And not just spotting but a full on heavy flow. My heartburn is outrageous, I'm never hungry because my stomach hurts all the time. There's been a painful feeling in my chest and throat when I swallow or drink anything! I just don't know what's going on!! I'm starting to become very concerned. I'm so sick and tired of feeling sick and tired.
