having checked out the menstruation cycle.. as copied from mestruation cycle
* Week 1. Week 1 is considered to start from the first day of bleeding. After the bleeding has stopped, women may be more energetic and have less vaginal mucus.
* Week 2. The mucus becomes wetter in the lead-up to ovulation.
* Ovulation. This occurs somewhere around day 14 on the ovulation cycle. The mucus is very wet. Breasts may be tender. There may be mood swings and cramps.
* Week 3. The mucus production slows down and the moods start to become more normal again.
* Week 4. This is the pre-menstrual phase. PMS symptoms may start, which can include bloating, cramps, headaches and mood swings.
I think it should be during the week 2 of the menstruation cycle when it is the start of the ovulation cycle. since the cycle is 14 days
the other picture which i search from the net tells it's best to get pregnant on the 9th - 15th day of the menstruation cycle

I think it's very uncommon. There is an easy way of confirming, however. If you miss more than one period and want to know why, but keep having neg tests, just ask your doctor to examine you. A quick internal examination will reveal whether or not you are pregnant.
