I am a 22-year-old female. I have an Hypothyroidism and take Levothyroxine.
On Monday night/Tuesday morning I had quite a lot of blood come out when I went to the toilet, enough to turn the toilet water red. I became worried and wanted to go to a doctor but I wasn't able to get an appointment. A few hours later I went again because I had stomach ache, but no blood at all came out that time, so I thought maybe I had popped a vessel or something and stopped worrying so hard. However, today it has happened again - when I went to the toilet I had blood with my stool.
The blood only comes with a bowel movement and stops quickly. I can't really tell if it is mixed in with the stool but it doesn't appear to be. It is usually a bright or normal colour.
The two times I have gone this week have been accumpanied by stomach pain, I don't know if that's a coincidence or not... I have had these types of stomach pains before, they are like intense cramps usually ending in diahrea, and when I have had them before - wether I have gone to the toilet or not - there has been no blood.
I have had this problem before, about a year ago, once or twice. I went to the walk-in clinic and they examined me briefly but said nothing seemed to be the problem. The blood just stopped and it hadn't happened until recently. My stools have been rather odd for a few months, diahrea then constipation, constantly different. I have been going through a lot of stress and change so far this year.
Obviously I intend to see a doctor ASAP, but I am really scared. I do feel I could have torn myself down there, but I can't rule out more serious problems. Does anyone know what all of this seems most likely to be?
