You are not always 2 weeks pregnant at conception, which is also known as fertilization.

Conception or fertilization often happens around week 2, but doctors count the pregnancy from the first of your last menstrual period, which makes you 2 weeks pregnant when you actually do conceive about 2 weeks later, so the conception occurs during the time that is labeled as 2 weeks pregnant by doctors.

Doctors begin counting from the first day of your last period for a 40 week pregnancy.

And about 14 days after last menstrual period around week 2 an egg is released and if sperm fertilizes the egg around this time, of week 2 or week 3, then conception occurs.

And so you're not actually truly pregnant until the fertilized egg implants in the uterus, which happens after conception.

So when you see the 2 weeks pregnant on a calendar, it often refers to the time that your body is preparing for ovulation, and conception is also likely to occur within that timeframe, which makes it seem like you're already pregnant at 2 weeks.

Then length of time that it takes to conceive on average is around 12 months.

Most healthy women or around 85 percent of women conceive within a year, and over half of women get pregnant the first 6 months of regular and unprotected

Your age also impacts your fertility significantly, which the chances of conceiving decreasing in your mid 30s, so women that are over 35 years of age are also advised to see a doctor after 6 months, if you haven't conceived and those under 35 should wait a year after trying to conceive before seeing a doctor.

The temperature that is best for conceiving is when your basal body temperature is around 97 F to 99 F, when it shows a slight rise of around 0.4 to 1F after ovulation, or 97 F to 99F when compared to your before temperature of 96 F to 98 F range, which is what indicates that your fertile window is right before this rise, which makes the slight increase signal that you've just passed peak fertility.

And this is while consistently hot environmental temperatures negatively affect sperm production and overall conception chances.

The 3 over 6 rule for ovulation is a guideline in fertility awareness for confirming ovulation using basal body temperature.

The 3 over 6 rule for ovulation is met when you have 3 consecutive days of elevated temperatures which are all higher than the 6 days preceding them, with the third high reading being at least 0.4 F above the highest of those 6 previous temperatures, which indicate ovulation has occurred and confirming the start of the infertile phase for that cycle.

To use the 3 over 6 rule for ovulation you take your temperature every morning at the same time, before getting out of bed.

And what you're looking for is a pattern where your temperature rises slightly around 0.5 F after ovulation which is due to progesterone.

You confirm ovulation when you see 3 days in a row where your temperature is higher than the 6 days before it.

And once the rule is met you know that ovulation has happened, and you're safe or infertile window begins for avoiding pregnancy.

The rise happens after ovulation, so it's a confirmation, and not a predictor of the exact moment.

The four signs that a woman is ovulating are changes in cervical mucus, a slight raise in basal body temperature and mild pelvic pain as well as an increased sex drive.

As a woman's ovulation is approaching, the woman's estrogen levels rise, which causes cervical mucus to become clear, thin and slipper and resemble raw egg whites.

This consistency in the cervical mucus helps the sperm travel more easily to the egg.

And as ovulation occurs, ovulation causes a slight but also detectable rise in basal body temperature of around 0.5 F to 1 F, which is a woman's lowest body temperature at rest.

This temperature increase during ovulation, often happens after ovulation has occurred and also remains elevated until the next period.

And some woman during ovulation also experience a minor ache or a sharp sudden twinge in their lower abdomen, often on one side, which is the side where the egg is being released.

This is known as mittelschmerz and the pain is often mild and short lived.

And as ovulation occurs, hormonal shifts during the fertile window, which includes a surge in the woman's estrogen and testosterone, which can result in a noticeable increase in sexual desire.

This is often also considered to be nature's way of encouraging conception during the most fertile period.

And other potential signs of a woman ovulating include bloating, light spotting, breast tenderness or even a heightened sense of smell, taste or vision.

Although not all women will experience noticeable ovulation symptoms, and the intensity can also vary from cycle to cycle.

But for accurate tracking of the ovulation, especially when you're trying to conceive, you can use methods like ovulation predictor kits or charting can also be used alongside of symptom tracking.

A woman's ovulation is when an ovary releases a mature egg, which is typically once a month, about halfway through their menstrual cycle, which is around day 14 of a 28 day cycle, which makes it the only time that pregnancy can occur.

During ovulation, a surge in Luteinizing Hormone triggers the release of the egg from a follicle in the ovary.

The egg then travels into the fallopian tube, where it's viable for fertilization for 12 hours to 24 hours.

And the uterine lining thickens in preparation for a potential fertilized egg.

And if no fertilization occurs, then the egg disintegrates and the uterine lining sheds as a menstrual period.
