Fertility Boosting

Lindsay
I have not actually been trying for 3 years but I felt you ladies would have some good advice for a sort of beginner :)
I tried for half a year about 3 years ago, then things fell apart with my partner at the time. Now I'm recently married and we've began trying, only 2 months so far that have failed. We are a lesbian couple with a private donor trying at home right now using the syring method. I don't want my donor to lose patience, even though I know he is aware we could try for a year and not get pregnant I know that it's a frustrating process for him too. 
I thought maybe you ladies would have some good advice on different ways to boost fertility. I'm currently cutting back on smoking and trying to quit, as well as getting into a more regular exercise routine to create higher fertility and promote general health for my body. 
What have you tried so far with things like diet or supplements that you feel are helpful? 
Thanks for any advice :)
