Chances of Getting Pregnant on Your Period

本质上，月经是子宫内膜的每月脱落。对于大多数女性来说，月经会持续三到七天。到了第三天，黄体酮和雌激素的水平开始上升，并开始重建你的子宫内膜。大约在第四天，卵泡成熟开始加速，这意味着卵巢将开始准备释放卵子。

除非你是一个非常早的排卵者（排卵的平均时间是月经开始前14天——通过使用基础体温图或排卵预测试剂盒来跟踪你的排卵),否则你的男人的精子在你周期的这个阶段几乎没有机会真正有任何卵子可以利用。

Your chances of conceiving: 几乎为零。然而，性交并没有什么坏处，一些女性认为月经是为了摆脱频繁的生殖性行为带来的严酷考验。

can live up to five days if it's trapped in fertile cervical mucus—so it behooves you to get a few of his swimmers in place. "One study showed that people who had sex only one time during this phase, even four to five days before ovulation, still got pregnant," says Steven R. Bayer, M.D., a reproductive endocrinologist at Boston IVF fertility clinic in Boston.

Your chances of conceiving: Good. An egg isn't technically released during this phase, but you'll want to step up your sexual routine in the event that you ovulate earlier than planned.

Chances of Getting Pregnant During Ovulation

Welcome to prime time for conception! No matter the length of menstruation, ovulation generally starts about 14 days before your next scheduled period. When it happens, your body temperature rises about a half a degree (detected by a basal body thermometer)—but bear in mind that this also takes place after you're already ovulating, which could be too late for conception. 

"That's where ovulation test kits become so helpful," Dr. Bayer explains. These kits detect a surge in luteinizing hormone (LH) that happens about 36 hours before you ovulate. After the test kit shows this surge, Dr. Bayer recommends having sex in the next 24 to 36 hours. Sperm can survive for some time in the reproductive tract, so it will be ready to meet the egg once it's released during ovulation.

Another good indication of fertility is a change in the consistency of your cervical mucus. "You'll see vaginal discharge that increases in amount and has the consistency of egg whites, signaling it's the perfect time to have intercourse," Dr. Bayer says. Test yours by sticking your index finger and thumb in your vagina to get a sample, then tapping your finger and thumb together. If the consistency is thin and spreads easily between two fingers, you're good to go.

Your chances of conceiving: High, if you have sex within 36 hours of detecting an LH surge. Any released eggs live no longer than 12 hours. In fact, it's best if his swimmers meet your egg within four to six hours of its release. Data show that having every-other-day sex is just as effective as doing it every day, so no need to go crazy getting busy every hour (unless you really want to!).

Also known as the luteal phase, this final portion of your cycle lasts a minimum of 12 days and a maximum of 16 days. Progesterone starts to rise, signaling that the ovaries don't need to release any more eggs this month. Your cervical mucus will dry up and create a plug to prevent any additional sperm from entering the uterus.

It takes about six days for any fertilized eggs to travel to your uterus. If one implants in your endometrium, you'll start to see the rise in human chorionic gonadotropin (hCG), the hormone measured by home pregnancy tests, within a week.

Your chances of conceiving: Low. Once the egg has been released, there's not much that can be done until next month. But there's certainly no harm in having sex if you're in the mood!

Don't sweat it if it's time for your cycle to start over again and you're still not pregnant. You may not have tracked your most fertile days accurately, in which case your guy's swimmers never had the chance to work their magic. The vast majority of couples who are trying to conceive do so within a year, with only about half achieving their goal by 6 months. Talk to your doctor or a fertility specialist about any concerns regarding your chances of getting pregnant.
