hey sweetie,
i had what sounds like a very similar problem last year. like you, i was too embarrassed to go to a doc about it for a few months. serafim has asked all the right questions - if the blood is dark brown, it means it is 'old' blood and is coming from somewhere high up in you, and this is bad and needs checking out immediately. go to a hospital.

if the blood is 'fresh' and there is a lot of pain, then it is possible that it is just a haemmerhoid or a fissure. a fissure is like a tiny little cut - kind of like when you split your lip? it hurts like hell. to me, it felt like sh*tting glass shards, it hurt that bad.

now, you have left it a long time, and usually fissures heal by themselves in 2-3 weeks, and i am guessing that that is what you have. but what you need to do is go to a doc, and they will do a physical, and tell you what is wrong. if it is a fissure, then they will give you an ointment that will help it heal. if it is a haemmerhoid, then they might refer you to a gastroenterologist.

if the blood is dark - then go to the hospital immediately. they will want to check it out.

just fyi - i had my 'issues' checked out by a gastroenterologist and there was nothing embarrassing about it at all. they give you an anasthetic so you are knocked out, so you don't remember anything when you wake up.

i hope you go to a doc/hospy today and come back and let us know how it goes. if you have any questions, feel free to pm me, if you'd like.
