worried about my negative HIV test

[unforgivenman87]

Hello Nursegirl,
i hope you not mad about writing u to you inbox
after looking at your professional answers and discussion, i tend to ask you a common question, maybe for you is common but i still would love to head your answer.

im a 24 male....in beginning may 2012 i had a non protected relationship with a girl that i started to date ( refering to her she was still virgin, she claimed to be clean...she went out state but we kept in touch) later on been on a serious relationship with my actual girlfriend that we no longer use condoms since mid may untill present, she also claimed clean and already tested, but my fear didn't let me believe her... but our last sex activity was on 14th july. i had no pain no symptoms that would makes me feel worried, but still i got freaked out after ive heard some stories from ppl. so i did some blood work with an HIV test with LAPCORP thru my Familly Doctor on 3rd august 2012...
3 days later i got the result from my doctor who told me that my results are Negative writen as follow; 1< relative to the negative cutoff.... non reaction
so its been about 13 weeks since my 1st relation and 11 weeks since my second relation.

i went back to the doctor asking him about all my blood work that i already had and my HIV and he confirmed me that im healthy

i kept stressed myself about the window period and how reliable are LABCORP regarding the test that i had  withing the time of exposure ( from both partners ) and how i can be sure that im 100% HIV free?????

also i would love to know if the period from mid May till now is enough to give an accurate result from LAPCORP?????

one last question in July i started a dermatologist treatment for my Alopecia ( loss hair ) and used to put a liquide on hair loss spot now my hair is growing up...is that treatment would change any HIV test result and gives a false negative ?

hope to get some help
thank you

we been together for 6 months Teak, and now we are getting married, i just can't ask her anymore as I already did and she got mad at me,im just  still worried, its been 2 months since our last sex and a month since my test, you know my story

Your negative doesn't tell you anything about her status.

[unforgivenman87]

so i can consider she is negative too ?

[Teak]

NO.

[unforgivenman87]

if she is positive, she would pass me the virus while ago before 3 month, as we no longer put condoms since April,so i don't suspect her cheating on me
my last sex activity with her was on 14 of july and i did the test on 3rd august, but as i said we been together for 6 month,i can't ask her anymore because she got mad at me last time

so do you think even after all this period i might be in a risk ?

If your last test was 3 months post your last unprotected sex with her you don't have a concern.
