This is going to be a little long... Sorry for it but I hope it will help.
The thing that helped me the most was first off read the book called Taking Charge Of Your Fertility... You can get it on amazon for pretty cheap or at any book store I am sure. It talks all about tracking your cycles to figure out when you ovulate because not everyone has a 28 day cycle and even then not everyone has the exact number of days for every cycle. I have a cycle that ranges from about 26-29 days so I dont always ovulate on the 14th day of my cycle.
So the second thing to do is start tracking your temperature every morning. Before you get out of bed or go to the bathroom or get a drink... Take your temperature about the same time every morning and track it. In the back of that book is a chart to chart your temperature or you can probably find one online that you can download. You will notice (sometimes not for every woman) your temperature might drop the day before you ovulate and then spike up the next day. That way you will know you just ovulated. It has to do with the estrogen and progesterone hormones that change during the different phases of your cycle. Also the second half of your cycle once you have ovulated is always the same number of days. For me it is 13 so I know if I go past 13 days and havent started a new cycle than I need to take a pregnancy test (although I hate waiting that long :) )
Once you start tracking your cycle you will know better when to expect ovulation and that is obviously the time during your cycle you will get pregnant. It is better to have sex every other day rather than every day because it gives the sperm time to build up in the man so that there is more released at once. If you are having sex multiple times a day it actually works against you because there is a lower quantity of sperm. You are normally fertile for a few days but only ovulate 1 day within your cycle. Sperm however can live up to 72 hours as long as the cervical mucus is the right consistency.
That is another thing you will notice changes during your cycle is your cervical mucus. Right after your period you wont have much at all. As you get closer to ovulating it will go from nothing to a lotion constancy that is sticky and work toward what is similar to an egg white that is stringy and has some elasticity to it. That is the best cervical mucus for sperm to travel thru and that is what sperm can actually live for extended periods of time in. Again that book will go more in depth of how to track that.
I hope that all makes sense. Feel free to message me if you have any questions.
