Hi, dear. I have gone through your question. I can understand your concern. you have had protected sex so risk is very low. But you should go for confirmatory test. If you gone through it then no need to worry. and no needto go for further testing. But if you have gone through antibody test then its results are not valid un this early period. so you should go for confirmatory hiv testing once. you can go with p24 antigen or pcr. hope i have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. wish you a very good health.
