Between trashing your birth control pills (a serious mojo downer!) and increased blood flow to your pelvic region, your engine is easily revved. And for the most part, pregnant women shouldn't worry about acting on their amped-up urges.
“Sex throughout your pregnancy is generally safe, unless you have a condition such as placenta previa or preterm labor,” advises Dr. Renee Horowitz, ob-gyn and sex expert in Farmington Hills, Mich. “And, it’s good relaxation.”
Tip: If nausea has squelched your desire, talk to your obstetrician about medications that can safely help you feel better.
