When you’re trying to conceive, it can feel like everyone around you is getting pregnant without even trying. It may be heart-rending, but knowing that most couples don’t get pregnant in one shot is important. For you to know your chances of having a baby, it is best that you know about the ‘fertile window’- the days where pregnancy is possible in women menstrual cycle. The’ fertile window ‘ varies among women depending on the length of the menstrual cycle. The ‘ fertile window ‘ is the day an ovary (ovulation) releases an egg and five days ahead. During this time, having sex (intercourse) gives you the best chance to become pregnant.
According to an OB-GYN at Women’s College Hospital and St. Joseph Health Centre in Toronto, Yolanda Kirkham that if you’re under 35, your chances of conceiving each cycle you try are 25 to 30%, eight to 15 percent if you’re 35 to 39, five percent if you’re 40 to 42 and one to two percent at age 43. Age affects not only fertility rates but also miscarriage rates, which rise after age 35 from around 10 percent in your 20s to 15 percent and up to 50 percent by age 45.
Ovulation occurs when the ovary releases a mature egg. The egg then moves down the fallopian tube to fertilize it. If sperm is in the Fallopian tube when the egg is released, there is a good chance of fertilizing the egg, creating an embryo that can grow into a baby. Technically, pregnancy is only possible if you have sex five days before ovulation or ovulation day. But three days leading up to and including ovulation are the most fertile days. During this time having sex gives you the best chance to get pregnant. A woman can no longer get pregnant during that menstrual cycle by 12-24 hours after ovulation because the egg is no longer in the fallopian tube. If you have sex before or after a fertile window, there’s almost no chance of getting pregnant.
Your ovulation should be tracked to improve your odds. Knowing when you are ovulating can help you plan for sex at the right time and increase your chance of becoming pregnant. According to a study published in the journal Human Reproduction in 2003, when 346 women between 20 and 44 years of age timed their intercourse to help them conceive, they had a 38 percent chance of conceiving in one cycle, a 68 percent chance in three cycles, a 81 percent chance in six cycles and a 92 percent chance of becoming pregnant in 12 cycles.
Overall, within one year of trying, 85 percent of women become pregnant. But if you’ve been trying without conceiving for a year, and you’re under 35, she suggests you’re looking for a consultation on fertility. If you are 35 or older, after just six months of trying, you should seek help because egg quality declines and medical conditions become more prevalent as we age, so there is a greater likelihood that you may need some help with fertility.
