The Scary Thing: "You have two vaginas."
What you may think: "Wait...what?!"
Why you can relax a little: This condition, also known as uterus didelphys, isn't common—it occurs only in about 1 in 3,000 women, according to the World Health Organization—and it isn't usually serious. It's a developmental abnormality in which two tubes in the reproductive tract (next to the fallopian tubes) don't fuse into a single vagina but instead remain separate. So you end up with two vaginas—and two uteruses and two cervixes, too.
One more thing: While it may present some fertility challenges, it doesn't mean you can't have children—one woman reported having two kids, a few years apart: one in each uterus.
The Scary Thing: "You tested positive for HPV."
What you may think: "Am I going to get cancer?"
Why you can relax a little: HPV, also known as human papillomavirus, is like the common cold of STDs. There are more than 40 different types of HPV, and it's become so prevalent that nearly all sexually active men and women get it at some point in their lives. While HPV can lead to cancer of the cervix, genitals or throat, the infection goes away in 90 percent of cases (usually within two years). Your OB-GYN will probably recommend regular screenings so she can monitor you. Women in their 20s and 30s, who are the most likely to get HPV, are also the most likely to clear it without any additional treatment, says Streicher.
One more thing: Cervical cancer, like most forms of cancer, is most treatable when caught early. That's why it's crucial to keep in touch with your gynecologist until your HPV tests come back negative.
