Actually, spotting after intercourse is a major symptom of chlamydia. A negative test for your bf is not proof you don't have it. So the first thing to do is to go to your doctor to be tested yourself, like it or not.
There are other things that can cause spotting or bleeding after sex, and you aren't helping yourself by relying on home remedies on the internet to diagnose and treat yourself.
What form of bc are you using? If you are having sex, you should be on some form of birth control if you don't want a baby. Even if you are on the pill, you should also be using a barrier method such as condoms to protect yourself against STD's unless and until you are in a committed exclusive relationship.
I want to put in my imput. Just because a guy tells you that he that he doesn't have anything does not mean that you need to believe him. The major important thing here is you need to wear condoms or some kind of protection to prevent diseases. I am not saying birth control that stops you from getting pregnant. You need protection from diseases. You are very young and at this rate without protection, you are going to be in trouble when you are older. AIDS is very rapid right now and there is no cure for that. You need to listen to these womens' advices and go get checked out. Don't blow this advice off that I am going to gice you. BOYS AND EVEN MEN WILL TELL YOU THAT THEY DON'T HAVE ANY DISEASES OR STDS TO GET IN YOUR PANTS BUT REALLY, HOW DO THEY KNOW. SOME STDS DON'T SHOW SYMPTOMS UNTIL LATER AND AIDS DON'T SHOW UP IN YOUR SYSTEM SOMETIMES UP TO 5 TO 10 YEARS. IT ONLY TAKES ONE TIME TO GET AIDS. DON'T TRUST. STAY ON THE SAFE SIDE.
I am bleeding during sex. Not after. afterwards Im completely fine! My boyfriend I know has none becaue I was with him when he went, but I suppose I can get tested to see. . . it'd be weird if I did. I've never had unprotected sex or anything like that..hmmmmmmm thanks though.
Bleeding during sex, bleeding after sex. Matter of semantics.
The point is, YOU need to be tested, and to have the matter addressed in a responsible way. And to discuss bc and STD protection with your doctor.
Just an FYI--you don't always have symptoms when you have an STD. My sister had chlamydia and had no symptoms at all. You need to be checked out to be on the safe side.

It is also a sign of cancer of the cervix. A good pap smear should clear up any questions.
