What to know when you're trying to get pregnant

You've decided to start a family, so now it’s time to get pregnant! You can use our ovulation calendar to track your monthly cycle to help you know when you’re most likely to conceive. And then be on the lookout for signs of pregnancy

In this topic, learn how family health history can help you find out about genetic conditions that you and your partner may have. You may want to talk to a genetic counselor or have some genetic tests. Knowing about health conditions before pregnancy can help you and your health care provider decide on treatments and care for you and your baby.

Don't worry if you don't get pregnant right away. Most couples who try to get pregnant do so within 1 year. If you’re having trouble getting pregnant, learn about fertility treatment.

How do you know you're pregnant?

Knowing the signs of pregnancy can help you tell if you’re pregnant. Here are some signs that you might be pregnant:

If you have any of these pregnancy signs and think you may be pregnant, go to your health care provider. The sooner you know you're pregnant, the sooner you can begin prenatal checkups and start taking good care of yourself and your growing baby.

How soon can I take a pregnancy test?

Home pregnancy tests are usually more accurate when your period is late - about 2 weeks after conception (getting pregnant). If they're done too early, they may say that you're not pregnant when you really are. This is called a false negative. That's why it’s best to take a home pregnancy test when your period is late. Carefully follow the test's instructions. Tests done at a lab or at your health care provider's office are more accurate.

I’m late for my period but my pregnancy test is negative. Why?

If you've taken a home pregnancy test and it's negative (shows that you're not pregnant), you may want to take a blood pregnancy test at your health care provider's office. A blood pregnancy test is more sensitive than a home pregnancy test that checks your urine. The blood pregnancy test can tell a pregnancy very early on. 


Pregnancy tests work by looking for the hormone called human chorionic gonadotropin (hCG), a hormone that a woman's body makes during pregnancy. If both a blood and urine test come back negative and you still have a missed period, talk with your health care provider. Things like stress, eating habits, illness or infection can cause changes in your menstrual cycle.

I’ve been trying to get pregnant for 3 months. What’s wrong?

Pregnancy may not occur right away, so there is no need to worry. For most couples, it may take up to 1 year to conceive. If you’ve been trying to get pregnant for more than a year, or 6 months if you're over 35, it may be time to talk with your health care provider. You and your partner can get tests to find out why you are not getting pregnant

Is it possible to ovulate without having a period?

Ovulation is when a woman's ovary releases an egg. This egg travels down into the fallopian tube. If you had sex without using birth control, sperm will swim up to meet your egg so that your egg can be fertilized. If no fertilization occurs, and after about two weeks, your body sheds the unfertilized egg, the uterine lining and blood and tissue that would have nurtured a fertilized egg. This is known as menstruation (your period).


You ovulate before you menstruate. But if you don't get your period, it doesn't necessarily mean that you haven't ovulated. For example, some women have irregular cycles. Even if you're very regular, once in a while your cycle may change. Therefore, it's hard to pinpoint exactly when you ovulate. If you don't get your period, you may want to take a pregnancy test.

What is the best time to get pregnant?

The best time to get pregnant is a few days before ovulation or the day of ovulation. This is because a man's sperm can live up to 72 hours after intercourse and a woman's egg is fertile for 12 to 24 hours after its release. If your periods are regular, use an ovulation calculator. If your periods are irregular, use one of the following. Talk to your health care provider to learn more about the most effective way to use these.

  • Purchase a basal body thermometer. Use it to take your temperature before you get out of bed every day. Your temperature goes up by 1 degree when you ovulate.
  • Check the mucus in your vagina. It may become thinner, more slippery, clearer and more plentiful just before ovulation.
  • Purchase an ovulation prediction kit. Use it to test your urine for a substance called luteinizing hormone (LH). LH increases each month during ovulation.

Have intercourse as close as possible to ovulation to improve your chance of getting pregnant.
