Just how quickly can you get pregnant? While some couples may conceive the very first month they try, most will get pregnant after three to six months. Others will need to try for up to a year.

What Are Your Odds of Getting Pregnant Right Away?

Researchers in Germany wondered how quickly couples can expect to get pregnant. They were especially interested in how common infertility and subfertility are.

Subfertility can be loosely defined as someone who takes longer than average to get pregnant, but eventually will succeed on their own without help.

The researchers felt that previous research on how soon couples can expect to get pregnant eliminated truly infertile couples.

Also, previous studies were biased because of their retrospective nature. In other words, the statistics were gathered after pregnancy was achieved and not collected from the beginning. What about all the couples who never conceived?

In this study, a group of 346 women were practicing natural family planning methods to get pregnant.

Natural family planning includes things like body basal temperature charting and cervical mucus observation. They use these tools to determine when their most fertile days are.

This group of couples knew which days to have sex if they wanted to get pregnant, so mistimed intercourse would not be behind failure to conceive.

The results are interesting:

  • Of the 346 women, 310 women conceived
  • The remaining 10.4%, or 36 women, did not get pregnant
  • After one month of trying, 38% were pregnant
  • After three months of trying, 68% were pregnant
  • After six months of trying, 81% were pregnant
  • After twelve months of trying, 92% were pregnant

    If you looked at only the couples that got pregnant eventually and eliminated the women who didn't conceive...

    • 42% conceived in their first month of trying
    • 75% by their third month
    • 88% by six months
    • 98% by 12 months

    What About Couples Who Don't Get Pregnant After One Year?

    What about those who don't get pregnant after one year?

    If you're not pregnant after one year of trying -- or after six months if you're 35 years or older -- then you should see your doctor. 

    While 10% of couples may not get pregnant after 12 months of trying, half of this group will get pregnant after 36 months of trying.

    About 5% of couples will try for four years and still not get pregnant.

    This group of couples was unlikely to ever get pregnant without medical help.

    I'm Still Not Pregnant. What Should I Do?

    If you've been trying for less than six months, don't fret just yet. Keep trying.

    If you're older than 35, and you've been trying for six months, see a doctor.

    Since age can be a factor, it's important you don't wait. You may still conceive on your own!

    However, it's best to get checked out. Make sure everything is okay.

    What if you're younger than 35, have been trying for six months, and don't want to wait until one year passes?

    Some doctors won't do fertility testing until a year goes by for women younger than age 35.

    However, if you have timed intercourse each of those six months, you may be able to convince your doctor to investigate sooner. One way to show this is with a fertility calendar. 

    If you've been trying for a year and you're not yet pregnant, you should definitely see a doctor.

    If you've been trying for two, three or four years, what are you waiting for?

    Some couples hold out hope, not wanting to face the music. I can completely understand this wish. But the passage of time could lower the chances of fertility treatments working.
