I wouldn't say to have sex everyday because it might actually lower your chances of getting pregnant due to your significant others sperm count. Maybe darling meant to have sex every day you're fertile. Don't stress out about it, that can actually hurt your chances. You should have fun with it. There are a lot of sites that can help you figure out which days are your fertile days if you have regular periods. Your doctor can also help you chart your cycles. Smoking can decrease your chances.
