So, onto today’s question: How can I predict my Fertile Window?
I am so happy you’re asking me this question.
You have probably heard it before: “it’s all in the timing”. If you and your partner are healthy and have no known fertility challenges, the single most important thing you can do to conceive successfully is to know when to have sex. This means you need to know when you ovulate and to time intercourse accordingly.
A study followed couples and found that untimed intercourse (which means, not knowing your fertility window) resulted in 10% chance of getting pregnant per cycle. However, timed intercourse (which means, paying attention to your fertility window) resulted in 25% chance of getting pregnant per cycle.
So, what does it mean to “get the timing right”? let’s talk about the basics of the female cycle.
The first day of your cycle is the first day of your period. During the 1 phase of your cycle,
called Follicular phase, follicles are developing in the ovary. A follicle is a fluid-filled sac that contains an immature egg or oocyte.
Eventually, one of these follicles will emerge as the dominant one. Once the dominant follicle has produced enough estrogen to reach a certain threshold, it stimulates a surge of luteinizing hormone (LH), which leads to ovulation. Ovulation will happen between 16 and 48 hours after the beginning of that surge.
Ovulation means that the dominant follicle ruptures, releasing a mature egg. This egg will travel down the fallopian tube to the uterus. It will survive 12-24 hours from the moment it was released.
So, during those 12 to 24 hours, while it’s travelling down the fallopian tube on its way to the uterus, it can be fertilized. How? 2 options:
So, this is what we call the Fertile Window: Given that sperm can survive up to 5 days in the female reproductive tract, and given that the egg can survive for up to 24 hours, your fertile window goes from 5 days before the ovulation to the day after ovulation: a total of 6 days per cycle. This is the optimum time for sperm and oocyte to meet inside your fallopian tube when, so your egg can get fertilized and travel down to the uterus, where it will hopefully implant and an embryo will start to form.
So, the million dollar question is: how can I predict this window?
Stay tuned – I’ll show you the top 3 methods to predict your Fertile Window next week.
