This *may* not be the right section but it seemed relevant.
I'm a teenager and for the past 1-2 weeks i've been constipated and there have been plastic-like "rolls" filled with something red (blood?) in my stool. Also I've been experienceda little nausea sometimes.
I'm going to the doctor monday but I'm very scared so it would be very much appreciated if anyone could guess what it could be.
