How to make a barren women get Pregnant

You've decided to have a baby! Now you're probably wondering: how long will it take to get pregnant, when should we have sex and how often? Find out here.
The Odds of Getting Pregnant
It's a common question: what are the odds that I'll get pregnant this month? For most couples trying to conceive, the odds that a woman will become pregnant in any particular month are about 15% to 25%.
But there are some caveats, and different things can affect your chances of getting pregnant. They include:
   - Age. After you reach 30, your chances of conceiving in any given month diminish, and they fall further as you get older, dropping steeply in your 40s.
   - Irregular menstrual cycles. Having an irregular cycle makes it tricky to figure out when you're ovulating, which makes it hard to know the ideal time to have sex.
  - Frequency of sex. It may seem pretty obvious, but the less often you have sex, the less likely you are to get pregnant.
  - Amount of time you've been trying to conceive. If you haven't gotten pregnant after one year of trying, your chances of becoming pregnant may be lower. Talk to your doctor about tests for female and male infertility.
  - Illnesses or medical conditions that can affect pregnancy.
Sorting Out Your Menstrual Cycle
Most women conceive faster if they understand their menstrual cycle. It's important to note that many women do not have regular cycles
Your cycle begins on the first day that you notice bright red blood -- not just spotting -- and it ends on the day before the next cycle begins. The length of a woman's cycle can vary from 21 to 35 days or more. If you notice that the length of your cycle varies by a few days from one month to the next, then your cycle is considered irregular.
Here's another common question from couples trying to conceive: How often should we have sex? In short, the answer is often.
A lot of couples trying to conceive spend a lot of energy timing sex, with mathematical precision, to the woman's ovulation. Theoretically, the approach makes sense. Recent studies have shown the window of opportunity for a sperm to fertilize an egg is pretty small: essentially, it's only the four to five days leading up to ovulation and the day of ovulation itself. Your best chances are on the day before and the day of ovulation. So the key would seem to be to have sex frequently in that five- to six-day window.
But while timing your lovemaking exclusively to those few days makes logical sense, it has some drawbacks -- primarily because your body doesn't always behave with clockwork regularity. Even if your cycle is regular, ovulation can occur at any time during the cycle. If you're having sex on the day you think you're ovulating, and you're off by a few days, you may be out of luck.
So the expert advice is to hedge your bets: have sex at least two to three times every week. And if you've got the stamina, why stop there? Studies have shown that as long as your partner has a normal sperm count; having sex every day of the month further increases your chances.
Going Off the Pill to Get Pregnant
People trying to conceive often wonder how long it takes for the effects of birth control medication to wear off. It's actually possible to become pregnant immediately after going off the pill -- as soon as the pill's hormones are out of your system -- although in many cases it will take a few months before ovulation begins normally again.
You should also know that it's safe to conceive right after you go off the pill. Women who conceive immediately after going off the pill are as likely to have a healthy baby as women who waited a few months in between.
