I Have Been Having Problems Trying To Conceive

Hi, My girlfriend and I have been having problems trying to conceive. We already have 2 kids and had a miscarriage in 2008. My girlfriend also thinks that she had 2 more miscarriages in Oct & Nov last year (2010). My doctor said that I should have a semen analysis done, and the results showed a Sperm Morphology of 93%. He referred me to a fertility specialist, who didnt sound like he knew what he was talking about. He advised me to stop taking Creatine and Protein supplements (which I m taking for weight training ), and then do another test. I m not sure that the Creatine and Protein supplements can cause negative Sperm Morphology issues, as everything I ve read suggests that they are actually beneficial to aid these types of problems, and because they are naturally produced by the body. So I was looking for a 2nd opinion. Also, I forgot to tell him I ve been using hair removing cream around my genitals, and was wondering if that could have affected the results at all ? He seems to think that my results werent accurate because I already have 2 kids and because my girlfriend had atleast 1 miscarriage, which means that unless I have suffered trauma to my genitals (which I havent) he cant think of any reason how the morphology could be that high. Also, in case he is right about the Creatine, how long should I wait after stopping my supplements before I should give another sample ? In other words, how long will it take for the extra levels of Creatine to leave my body and not affect my test results ? Edit: By the way, I forgot to mention that everything else was perfect in my Semen Analysis results.
