Additional Info: Is It Safe to Have Sex During Pregnancy?

One of the most universal concerns of couples (especially husbands) is whether they will hurt their baby when having sex during pregnancy. As mentioned previously, as moms-to-be enter the second trimester, they experienced increased libido or drive to sex.

This is due to increased blood flow into the sexual organs including the breasts. Mothers during early pregnancy have a lesser urge to sex due to extreme fatigue and other disturbing symptoms of pregnancy. But doctors say that there is no need to worry about sex when you are pregnant.

They explained that babies won’t hurt during sexual activity. They are protected by uterine wall, amniotic sac[2] and amniotic fluid which serve as barriers from any external factor.

In addition to that, the opening of the uterus is protected with a mucus plug. To correct the fallacy, orgasm won’t trigger labor. Although some might experience uterine tightening when reaching the climax — yet, this is still normal.

Nevertheless, doctors advise avoiding lying flat on your back during sex so as not to compress the vena cava. Compression of this part can make you light-headed and decreased the oxygen supply to the baby.

Nevertheless, pregnant mothers who have placenta previa[3], cervical incompetence and those who are experiencing preterm labor and vaginal bleeding are advised to abstain from sex during this time. Ruptured membranes or when the water is broken is also a contraindication to have sex during pregnancy.
