What can I do to increase my chances?

I had a miscarriage in December and I'm desperate to get pregnant again.  We've been ttc since February and it hasn't happened yet.  I do opks, temping and this month started taking vitamin d and b complex.  I also started pomegranate juice.  Is there anything else you've heard of/recommend?
