Conception Calendar
From LoveToKnow Pregnancy
If you have been trying to get pregnant, you may want to create a conception calender.
What is Conception?
Conception cannot occur without ovulation. Ovulation occurs when you release an egg into your fallopian tubes. There it waits to be united with sperm to create a fertilized egg. Conception occurs the moment the sperm and egg join. Once the egg is fertilized, it continues down the fallopian tubes and implants into the uterine wall. This process takes a couple of days.
If you take a home pregnancy test before the fertilized egg implants into your uterine wall, you will get a negative reading, even though you have actually conceived. Home pregnancy tests measure for the pregnancy hormone hCG. This hormone is not produced until the fertilized egg implants into the uterine wall.
Creating a Conception and Ovulation Calendar
A conception calendar is very similar to an ovulation calendar. Ovulation occurs about the same time in your monthly cycle. You can chart ovulation using a calendar and simple calculations.
Creating an Ovulation Calendar
To create an ovulation calendar, you need to start by noting the first day of your period for at least six months. After six months, you can figure out the length of your cycles. Your cycle goes from the first day of your period until the day before your next period begins.
Find your shortest cycle and count of the number of days in it. Subtract that number from 18, and take the difference. Starting with the first day of your next period, count that many days forward. This will give you the first day you might be fertile.
For example, if your shortest cycle is 29 days long, you subtract 18 from it to get 11. If your next period starts on Oct. 3rd, add 11 days onto it. So the first day you might be fertile is Oct. 14.
Next, find your longest cycle, count the number of days in it and subtract 11. Take the difference. Starting with the first day of your next period, count that many days forward and. This is the last day you’re likely to be fertile.
For example, if your longest cycle is 31 days long, you subtract 11 from it to get 20. Using the Oct. 3rd example, add 20 days onto it. So the last day you would be fertile would be Oct. 23.
This gives you an ovulation window of Oct. 14-Oct. 23. Of course, it does not give you your exact ovulation date; no one knows exactly when they ovulate.
Creating a Conception Calendar
If you know about when you ovulated, you know about when you concieved. After ovulation, the egg only survives for about 24 hours. So if according to your conception calendar, you are fertile Oct. 14-Oct. 23, conception will occur during those dates. Since the egg can survive for 24 hours after ovulation, you need to add an extra day onto your ovulation window to determine your conception window. For example, if your ovulation window is Oct. 14-Oct. 23, you may have your conception calender would indicate you concieved Oct. 14-Oct. 24.
Chinese Conception Calendar
The Chinese conception calendar is an interesting tool based on an ancient Chinese statistic chart. By imputing your lunar age and the month of conception based on the Chinese lunar calendar, it can tell you your chances of having a boy or girl. This chart was discovered in a tomb, and was probably developed in the thirteenth century. The original is on display at the Beijing Institute of Science in China.
Reports vary on how accurate it is. But it may be an amusing game to play with your family and friends, especially if you are waiting for the birth to find out if you are having a boy or girl.

Kris,
it can be either. Some women go right back to a normal cycle after stopping the pill while other can take a few months. The symptoms you mention can be some of the early signs of pregnancy, but they are pretty early to occur if you are pregnant. Since you stopped the pill mid-cycle, I suspect that your body is just going through a lot of changes as it gets used to the change in hormone levels.
-- Contributed by: HollySwansonHi there, I used to be on Microgynon, had a period sept 13-18 but stopped the pill on the 23rd, then i had a period oct 7-12, and had unprotected sex with my bf from oct 13-18, the time where the ovulation calender says I'd be ovulating.
Now i having all these signs, cramping on my left side ( lasted about 3 days)nausea (lasted 5 days initially but still happens once a day), lightheaded (2 days), sore nipples (still ongoing), my appetite is increased , weight gain, MOODY!!!. Can this be the effect of coming off the pill? Could I possibly be pregnant? please please help! -- Contributed by: KrisDanielle, unless the period you had on 10/19 was Bleeding During Ovulation instead of a real period, you probably didn't get pregnant on October 18. With a period on 10/19, you should have ovulated and conceived around 11/2.
But, that doesn't seem to match up with the timeline given to you during your ultrasound. I calculate you being 11 weeks pregnant. You may want to talk to your doctor about this difference or ask for more measurements in an ultrasound.
