Best to get tested to curb your anxiety and fears. With this said however, your actual risk really didn't exist since you used protection.
HIV symptoms are the same as those found in a million other things, many of which are not serious.
Hi Raji,
This is based on material in these forums from Doctor's and others like ourselves. As long as the condom did not fall off during intercourse, you should be fine. Symptoms are never a reliable indicator. The window period for ARS seems to be 10 to 20 days.
Also, even if the condom did fall off, your chances of hiv infection would be 1 in 2000 if circumsized, and 1 in 1000 if uncircumsized. The only way to know for sure is to get tested and find out. I wish you the best but I believe and hope that you are ok.
