Dear all,
I am 24 y.o. male student.
My first girlfriend, ~3 months after we
started kissing, had high fever for
several days, and was treated as having
pneumonia, with antibiotics. Later after
half-year she started having low fever
constantly and was diagnosed a
mononucleosis.
My current girlfriend, after two months of
we started kissing, in June started having
high fevers and developed an enlarged
spleen after. Hospital diagnosis --
mononucleosis, she gradually but first
vaguely started developing antibodies,
now, after I was away from her for 3
weeks, last week she is having spleen
retraction and less pain.
My mononucleosis (monospot, as well as HIV
and hepatitis) tests are all negative.
I have done one more - mononucleosis
antibodies test (IgM and IgG), which
showed 0 concentration of IgM and IgG.
Can this be true that I am "clean"
(although both girlfriends started having
it) and I am susceptible to infection,
although did not get it yet. I have
chronical tonsilis for last 6 years (very
easy to get tonsillitis after a cold blow
to neck, but goes away quickly with JOX
iodine-based spray) and I frequently catch
cold, but maybe my immune system is still
strong enough. And still I'm not a
transmitter, as tests claim.
Is it also viable that I must restrain
from mouth-to-mouth/oral-sex relations to
my current girlfriend, as her family
doctor suspects me re-infecting her over
and over again without me actually getting
ill and/or developing antibodies? Which
would be a disaster

I am feeling fine,
no expressed fatigue or fevers, nor other
symptoms. And have no idea, if I'm a
carrier, or I am clean or a
dunno-what-to-think..
Should I give in to my gf, so I could
become sick and then develop immunitet
against future middle-aged infections,
which may wind up worse.
Or are the tests results false-negative,
meaning that I do have chronical
mononucleosis (with this mild tonsilitis
~2-3 times per year simptom in mind)?
Thank you very very much in explaining
this case. Would really appreciate, as now
I am completely lost...
