today marks 2 months with no period

I haven't had a lot of answers from my Drs, most have said because I haven't been trying very long (6 months) and my periods are normally regular to not stress. They ordered blood tests and said everything came back normal. I had a negative blood test when I was about 10 days late for my period. I have normally 33-35 day cycles, so today is day 62. I had a positive pregnancy test, but now I'm thinking it was an Evap or an ident, it's still there, very PINK looking one month on, but negative tests since, and only that one positive test no others. So I am thinking it's a false positive. I am getting very emotional and don't know how to talk to my husband about how this is making me feel. Has anyone had this happen? I don't want to get my hopes up but could I still be pregnant? I am having some sharp pains in my lower left side especially. Please help I am at breakig point emotionally with this.
