Hi ladies, I just found out that I'm 3weeks pregnant after trying to hv bb for 2-3months... I uses Basal Body Temperature (BBT). This technique is also good if you have irregular menses.
The homework is to get three things.
1. First body temperature b4 u get out of bed, make sure same timing every time u take
2. Check your cervix fluid, if it is like egg white, go hv sex.
3. Cervix position and softness. Whether it is high up or soft or opening. (Low, easily reach n hard n close, it means is not fertile)(High up and hard to reach, soft and open, it means you are likely to ovulate -egg coming and very fertile). This require you to insert your finger into ur V to check everytime you shower, rem to wash ur hands n trim those nails.
Go buy a theramometer with 2 decimal points so more accurate. Next, come out with a chart to mark your daily temperature.
1st day of your cycle is the day your first day of menses. There are 3 phases to your normal cycle, Pre-Fertile phase, Fertile phase (where your temperature will b higher then normal), Luteal Phase where your egg will incupad and implant to your womb.
Here is an example of my chart this cycle:

Try to have sex during the time where you ovulate, this is where you will see a jump in your basal temperature and it comes with egg white discharge. Is time to listen to your body and u will learn so much more.
If your menses is coming that day, normally your temperature will fall back down to your begining temp, that is when u need to prepare to wear ur pad that day. Hehe.
If you are pregnant, your temperature will rise all the way... this will be what you are looking for. I did my pregnancy test on 11dpo n it was negative but did it again on 18dpo and I'm pregnant.
Hoep this help. =)
