If you hope to get pregnant fast, you've got lots of company. For a variety of reasons, from simple impatience to excitement to hoped-for-birthdays, some couples are eager to conceive right now.
Here are some things to keep in mind:
Be realistic. Remember that while it's possible to get pregnant the first month you try, it's not highly likely. If you time things right and do whatever you can to optimize conception (and there are no fertility issues in your way), you should be able to get pregnant in three to six months.
Know your TTC basics! If you know about ovulation and timing sex, and you know how to increase the likelihood of conception, you increase your odds of getting pregnant fast. So study, study, study. Then have lots of baby making sex!
However, if it takes longer than six months (if you're over 35) or more than a year, then speak to your doctor. Or, if you have any symptoms of infertility, speak to your doctor before you spend too much time trying. You may be dealing with infertility, and the sooner you get help, the better your chances for treatment success.

Hi Rachel! I’m doing research for a project for my health class in college and was hoping you could answer a question for me. I heard from a doctor a couple years ago that eating kiwi helps the conception process. Do you know if this is true? I feel like he may have been joking…lol. Thanks!
