As long as your pregnancy is proceeding normally, you can have sex as often as you like. A woman's sex drive may go down during pregnancy as hormonal fluctuations, fatigue, back ache, weight gain and nausea might sap her sexual desire. Although most women can safely have sex throughout pregnancy, sometimes it's best to avoid sex if you have a history of preterm labor or premature birth, unexplained vaginal bleeding, waters breaking, cervical incompetence (open mouth of the womb) or if your placenta partly or completely covers your cervical opening (placenta previa).
Although many couples worry that sex during pregnancy will cause a miscarriage, having vaginal intercourse is known to be safe during pregnancy. As long as you're comfortable, most sexual positions are also okay during pregnancy. As the pregnancy progresses, you may try out different positions to find what works best for you.
