Any ideas as to what's wrong with me?

Please, don't go on the internet looking for a diagnosis, just go and see another doctor if you're not happy with their diagnosis. But hey, just throwing it out there, if you notice there is blood in your urine or it's a dark colour like coke, then screw the doctors and just go to hospital.

Clymidia for sure. Just because you haven't slept around doesn't mean he hasn't! Get tested for it today! It has to be a specific test for it-it wont get picked up on a normal (general) STD test.

Go to a doctor. If it's a burning pain it might be UTI and you better use a condom please and only have sex with a lover.

Actually just throwing it out there again, have you had a pap smear? If not, you probably should. No matter how old or young you are, if you're sexually active you should get it done.

Could be a pelvic/bladder infection, cancer (VERY VERY unlikely) or some other obscure condition that not many know about.

I hope things get better for you and that they start happening sooner rather than later.

Go to a doctor!

Bodily wastes should never be dark....

I was got sick when I was in europe and my shit was Pitch Black!

This was after I got a negative blood test for a blood clot. I never did really find out what was wrong with me.... and I still get some of the symptoms from time to time.....

Yah, that dark coloured urine? Is possibly blood in your urine. Go see a freaking doctor or go to a gyno straight away please. It could be something serious.

Nothing has been up there while I was on treatment. I came off the third and final anti-biotic a few days ago, yesterday was the first time me and my partner had done anything since the start of the first treatment. I take good care of myself when it come to hygiene, as does my boyfriend. I've checked for anything unusual in there, and everything looks fine, no lumps and bumps, no funny discharge.

*not quite as dark >.<
my bad there. I was worried that it could be thrush, because the tablets could cause that, but are these the right symptoms for that?

Thrush... Yeast infection! Get some yogurt and cranberry juice!!

Go see another (different from the one you had before) doctor, gynocologist, ect. and hopefully they can tell you what is wrong and how to fix it.

It is a dark colour, but quite as dark as coke. It smells strongly too.
I'll have to take your advice on the pap smear. That's something I'm yet to do.
I've been to a doctor on several occassions now, and I'm fed up of their bullshit.
Also, it deffo isn't clymidia, both me and my partner were tested for it and we're both clear.

You make the infection start all over again or prevent the antibiotic from fighting it off correctly and eliminate the bacteria from your bloodstream completely by sticking in there dirty fingers and being a careless nastyvdirty fuck. That way you are going to develop an antibiotic resistant infection then only radiations will be useful in fighting off the infection. That's the thing about antibiotics. They help getting rid of the bacteria but do not really make you any more resistant to it. So you can catch the same infection over and over again from the same sources you caught it in the first place. Unless you keep everything clean and sterilized. Which kind of infection is it? I am guessing staphys. Tiny little bastards. Are you sure you followed the antibiotic therapy without any errors? If so there might be some other thing going on, making it more likely for you to ger these infections. Like an abscess or a polyp in your vag. But usually very vigorous stimulation along with poor self higiene habits can be enough. Example: you or someone else sticks his fingers in there with dirty nails, without noticing he causes a tiny lesion in there, germs from under his fingernails get in and BANG! You get an infection. If you got a strong immune system and can fight off the infection fast then it might not cause much distress and heal on it's own. But if immune defenses are somehow below the necessary, it spreads and becomes very difficult to deal with. Yeast or clamydia eventually die out after the treatment, they rarely become so unresponsive to treatment.
