Norethisterone
 

ive just noticed blood when i went to the toilet but im not due on for another 2 weeks, im wondering if its from using Norethisterone but ive finished taking them about 3 weeks ago and had a period since, i dont know how long the side effects last for. if anyone has experienced anthing like this could you please let me know.

What colour was the blood? Do you have any digestive disorders or an eating disorder?

You need to see a Dr about this, to me it seems unrelated to the medication, but a Dr still needs to find out the cause of the bleeding. It could be piles/hemorrhoids [however even piles may need treatment] if it is just when you go to the toilet and the blood is red/fresh, but it could also be a sign of something serious.

If the blood is dark and tarry looking, I would see your GP today/call NHS direct for advice or pop along to A and E, anything that means you seek medical advice asap.
