Pregnancy is a weird thing. One minute, you feel like a hormonal 20-ton truck; the next, you feel all Life-Giving Earth Mother. One week, you can't even bear the thought of being touched; another week, you're totally in the mood, big belly and all. When this happens late in the pregnancy — as in, up to the 40th week and even beyond your due date — you may wonder not only whether it's safe, but also which sex positions are best in late pregnancy.
Here's the good news: Unless your doctor advises against it for a specific reason (such as placenta previa or leaking amniotic fluid), it's perfectly safe to have sex throughout your pregnancy, right up to the end of the third trimester, according to the Mayo Clinic. Even if you're beyond your due date, you won't put your baby at risk; your uterine muscles and amniotic fluid keep the little one cushioned, and penetration doesn't get close enough to touch your baby, assured BabyCenter.
Whether you're hoping to move things along, or just want some final intimate moments with your partner before those long nights of feedings and everything else, knowing which positions are best will make the experience both comfortable and enjoyable.
