I'm a woman in my early 40s and I was seperated from husband. During seperation, I was involved with a male and had unprotected intercourse/vaginal only with no ejaculation inside on 7/30/09 n oral with ejaculation/spit n rinsed mouth on 8/23/09. I tested @ 5 months post exposure, Jan. 2009, for hiv and syphillis-negative and @ 6 month mark, Feb. 2009, for hiv, syphillis, chlamydia and gonnorhea and was negative. My concern is that in Nov.2009 I had a ear infection and was given Bactrim. I took it for only a few days and then was given Tamiflu because I developed the flu. Come to find out it wasn't the flu but an allergic reaction to Bactrim. Could the drugs that I took have masked a syphillis infection causing me to have a false negative? I'm having symptoms: severe hair loss, a cut near my anus which I thought was from cleaning myself too hard with toliet paper. The cut is still there but its healing...I've had the cut for like 3-4 weeks. I have since reconciled with my husband and am petrified that my tests were all wrong. Btw I do have hsv2 and I did disclose to my fomer partner. I also insisted that he be tested for all stds prior to our engaging. He said he tested and was negative but I never did see the actual results. Only saw his last rapid hiv test which he took on 8/29/09-negative, which was 6 months from his last sexual encounter. Should I retest? I'm extremely worried.
