Could it be chlamydia?

i had sexual contact with my boyfried with no clothes on but he didnt go in me but i think he might ejaculated near my vaginal area..i been having really bad pain in my pelvic area and i was bleeding for about four days i bled about 3 weeks after this happened and i read somewhere that these are chlamydia symptoms...anyone can help answe my question?

STD's are easy to spread, and not necessarily just through sexual intercourse. ANY direct skin contact can cause transmission. Herpes is spread this way, even when there are no physical symptoms.

Go to a clinic and get tested.

any std.. it can be any sexually transmitted disease or maybe something else.. get checked out b/cuz its important that u do.. calm down, find out first
look up stds.com it will give you a list and the symptoms
time to visit a gyne ASAP.

But why didn't he go in? If there was pain already in the first place, it might not be STD at all. Nevertheless, you still need to visit your gyne because the bleeding and pain is obviously not healthy for you.
Go to the doctor.
you do not need penetration to contact std. u should see a doctor.
don't self diagnose. go see a doctor
