My other How To article discussed how to add realism to your stories when making a character become pregnant. I have been asked to extend this topic and discuss how to make stories more believable when you have a pregnant character.
Readers like to have realistic stories when it comes to the details of specific things. The sex can be over the top, but if you make a mistake on certain details, it ruins the story for some readers. Adding a pregnant character can be difficult if you have never been pregnant yourself or have never been around someone who is pregnant. Pregnant characters can occur in romance and erotic couplings stories, especially in situations where a one night stand results in an 'oops'. Stories revolving around the breeding fetish are also common and when you are writing novel length stories, you might decide to make one of your characters pregnant to further your plot.
First Trimester
A woman will find out she is pregnant by either a blood or urine test. You can buy a urine test at the drug store, but a doctor's office may also test for pregnancy in that way. A blood test can also tell if a woman is pregnant, but that can only occur at a doctor's office. The urine test shows a positive right away, however a blood test can take a few days.
Once a woman knows she is pregnant, she might realize that she has signs and symptoms. The list of signs and symptoms of being pregnant is long and detailed. During the first trimester a woman may have swollen breasts, high sex drive, nausea (not just in the morning), heart burn, and have a lack of energy.
