I'm a 16 yr old female, average weight and height, Over the last 4 months, i have been getting bloody stools, and heavy bleeding everytime i go. Like to the point where the water in the toilet bowl is thick red. Also i have been needing to go for 'number 2s' less, and when i do try to go it comes out strange (like i feel like i'm constipated its hard to get out, but once it comes it out its like diahorea) and with the blood.. it hurts after a while too... Also i never get full now.. my body just keeps wanting me to eat even tho i get really bloated.. I've tried changing my diet several times but nothing works... I'm not sure whats wrong with me and was hoping sumone culd suggest sumthing or help before i go to the doctors
