dear doctor
i am 29 male.
i had a exposure with a sex worker on 1st may 2012.
though i used a condom but unfortunately didnt use it properly. i removed condom after few strokes of intercourse (for a hand job activity) and re-used the same condom after some gap. i am not sure that if i used the same side or not. since it was my first exposure, so i wasnt very sure of things. also, their was no smooch/ kissing involved in the act.
after 10 days of this, i noticed a change in my bowel movements (frequent) and had some bad throat. i went to a GP, and he advised me to take PEP. i took PEP for 2 days and then stopped after advice of some other GP.
after that i did CMIA test on (always from the same lab)
23 may/ 10 june/ 23 july/ 10 aug. 10 sept/ 18 sept----
index value---- 0.11/ 0.25/ 0.33/ 0.55/ 0.57/0.52.
cbc/ lft/kft are normal over this period.
changes in overall health:
bowel movements are more frequent (twice a day--i was a chronic constipation patient before this)/ acidic stomach as never before/ recent eye infection (august)/ lymph nodes pain remained till june end/ these days a strange headache is hitting me. near neck and behind eyes. it keep coming and going. no fever is noticed. i am not on medication of any sorts.

please tell me if i have any reasons to worry? i am planning to get married. please tell me because one more step (1st one to go for sex with a prostitute!) could hit someone else's life too.
