On average, you get less than 10 minutes of actual face-time with your doctor. So naturally, they can't tell you everything you need to know. And since many women rely on their OB-GYN for a good chunk of their health care, we dug up some intel your gynecologist might not have on her to-be-discussed priority list.

Wash your hands often to prevent birth defects

Eighty-six percent of women have never heard of CMV. If a mommy-to-be picks up this extremely common virus (you likely come in contact with it on a daily basis) while pregnant, she can pass it along to the fetus. This can cause blindness, deafness, severe disabilities, and death. One in 150 children are born with CMV—more than Down syndrome, fetal alcohol syndrome, spina bifida and pediatric HIV/AIDS.

The good news is that it can be prevented by simply washing your hands well and often—especially if you are around kids (and, as a result, changing diapers).

Know your breast density
Mammograms are likely to miss tumors in women who have dense breast tissue (because it shows up white, just like a mass would)—yet only 9 percent of doctors discuss breast density with their patients. Dense boobies also might make it more difficult to ID a suspicious lump during a self exam. If you have a family history of breast cancer, ask your doc if you should have imaging done to determine your breast density. If you are dense-chested, have her mark it in your file. When the time comes, you may be better off having an ultrasound (or other imaging) as opposed to a mammogram.

Pee before sex

While we've heard that it's a good idea to urinate post-nookie, we recently learned that you should actually hit the potty pre-deed as well. Turns out, when your bladder is full, there's more room for bacteria to find their way in.

Ditch the p.m. tampon

It's not going to kill you, however, if you're prone to UTIs, consider going with a pad instead (especially on weekends when you're likely to sleep in). Blood breeds bacteria, so the longer you go without changing it up, the more likely you are to develop an infection.

Struggling with PMS? Besides being period-free, women who take birth control pills continuously (by skipping the placebo week or using an extended regimen) may end up with fewer headaches, less pelvic pain and milder mood swings than those whose pill plan results in monthly bleeding, a study in Contraception shows. The nonstop dose keep hormones steadier and side effects at bay. Have infrequent periods? Better ask the doc about polycystic ovary syndrome.

Postpartum symptoms can begin long after you give birth

Studies show, in fact, that postpartum can manifest itself up to a year later. If you feel anxious, sad, withdrawn, etc., don't blame it on lack or sleep or simply making the transition into mommy-hood. This isn't sorority rush—there isn't a requisite initiation. Get to a doctor ASAP.

Some women are unhappy with the birth itself. Check your symptoms to see if you could have anxiety or depression. You're not alone if you do: One in three women will suffer from anxiety, and one in five will have clinical depression.

Wear a panty-liner during exercise

Sweaty workout pants are a breeding ground for bacteria. Either shower and change, pronto, or wear a panty liner to soak up some of the sweat and buy you time until you get a chance to hose off.
