hello and i would advise you go and get checked out and please stop having unprotected sex.
you could have cervical infection and i need to say this but Why have unprotected sex when just after an abortion through doin probably the same thing.
there are so many women desperatley want children and can,t through medical reasons beyond them.
Protect yourself from secondary sexual infections and pregnancy go see your doctor.
If you have an underlying problem why you do this please talk to him/her about it.
