I'm afraid not. This is going to be difficult news for you. You have pelvic inflammatory disease. It's a sexually transmitted disease. Illnesses like this one are only caused by having unprotected sex with someone else who has the same illness.
Unprotected sex means sex without a condom.
But I only make love with my husband. He doesn't necessarily have to feel ill, Swanti. People often don't. But if you've only been with him, then he must have passed the infection to you. You're very upset at this news, I can see.
