Help! lots of questions!

We are totally new to this. My consultation appointment is a week from tomorrow. I have been on prenatals for about a month and have started eating healthier and doing some mild exercise, (but I will say I wasn't overall unhealthy before) tracking ovulation with Advanced OPKs. What else can I do?? Success tips very much appreciated! I want to give this the very best chance on the first try! Also, we will be using an OB/GYN for our IUI (as it is illegal in our state to inseminate at home...ridiculous) and was wondering if anyone had any insight as to how going to a fertility clinic may differ from using her.
