text: couples with mono? my boyfriend was diagnosed with mono about 2 weeks ago via blood test, but he was showing symptoms earlier.  i was tested a week ago and came up negative for mono.  i'm still feeling very nervous about mono and am wondering whats the likelihood of me contracting mono from him.  (i.e. is there a tendency for couples to get it around the same time??) did i get tested too early?  i'm really scared. if you don't have any symptoms still then you probably dodged that bullet.  you may as well get tested again anyway.
