If you want to get pregnant and you're not sure where to start, a good first step is getting familiar with your body.
Pin pointing your ovulation time frame can be key. You can do the math yourself but like 9th grade algebra, a calculator makes it easier. To find out how,
On sites like BabyHopes and WebMD, simply enter the first day of your last period and how many days are in your cycle (usually 28) and your probable ovulation dates will reveal themselves. Some calculators, like the one on Parenthood.com, will even show you the astrological sign that corresponds with the baby's approximate due date. So if you don't want a Scorpion baby, then you'll know to save the baby making for next month!
Obviously, there are other factors that play a role in the whole baby making process, but knowing your body is a good starting point.
