It's been proven that having sex every day really doesn't help. I did the "shuttles (sp?) method" and only had sex on the three day's farthest away from my fertile day because I wanted a girl. Worked for me. Haha. But, I would just make sure you're eating heathy, staying active, and having sex once to twice a week (even away from your days of ovulation.) to enhance your chances. Good luck!
Use Glow to pinpoint your fertile days and have sex during that week. Also Google the sperm meets egg plan. That's a great way of knowing when and how often to have sex.
