thank you for this opportunity. i had sexual intercourse with a sex worker. i used a condom properly. but am scared that i might have contracted the HIV virus. the internet is telling me that a condom can only provide 85% protection. and it is also telling me about HIV symptoms. my lymph nodes are not swollen, but i had two night sweats in the past three weeks. this is my fourth week after possible exposure. And also how soon can i get tested? your medical opinion will help me greatly.
