Why can't I get pregnant?!

Autumn
Ok getting pregnant is going to take me a little longer than most women anyway because I only have one ovary and oveulate every other month. I ovulated this last month and we went at it like rabbits but AF is here. Today sucks because we can't try this month. Now we play the dreaded waiting game. What vitamins can I take to help ovulation? I was also told some kind of cough syrup can help if you take it once a day as soon as your period starts? Just help me ladies!! I need more than baby dust I need a miracle...
