[zonal]

Hi... I had few protected sexual enconter in past. The last one i had was about 5 months ago. I recently had a medical tests which includes HIV test as well and my medical report was fine and there is no any infection.I am very hypochondric and everytime after having protected sex i went for hiv test and it was negative. basically window period for hiv test is 3 months and i tested at 5th month and obtained a negative result. Nowdays my main worry is that my mind keeps telling me and imagine that i also had a sex in recent time(2-3 months ago) after that episode which happend five months ago. Is this possible that i had sex 2 months ago and i forget? and i remember the sex which i had 5 months ago.The sexual encounter which i imagine i had recently actually happened more than 1.5 year ago but still my mind is trying to make me believe that i had it recently.

Your main problem is you worry too much.  That's what you need to work on, perhaps through therapy.
