Doctors have told me that you shouldn't have sex everyday over and over again if your trying to concieve, sperm lasts in the vagina for 5-7 days anyways. They also say not to get up just right after sex, to go to the bathroom, etc.
The only reason why i, and other people have been hard on the girls wanting to concieve, is because they're young and think they can raise a baby with a paper route job. If your financially able and if you're physically and emotionally ready for that then go for it.
But money doesn't buy love, nor will it buy how you treat your child.
It's about these girls realizing they can make a better life for the child they want to create, a few years later in life, but instead they're being selfish, still knowing they can make a better life for their baby if they wait, but they chose not to because they want it.
