I am trying to conceive and wants to know how often should i have sex ?

Daily: Some couples get pregnant after one episode of sex. We call them lucky, if they are married, settled down, and wanting to have kids. The majority of couples may not be so lucky, but they can try having sex once or twice a day from about 3 days before expected ovulation, to a couple of days after expected ovulation. (Nobody knows exactly when she will ovulate.)
