Should 15 year olds who choose to keep their pregnancy ask for help?

Ok. So here's the truth. I absolutely hate teen mothers who are 15 and expect their everyone to help them out because they got pregnant. Here's the truth. If you're going to be having sex at that age I suggest birth control. Seriously. You need to be on birth control to at least prevent pregnancy although I know not all birth control is 100%. I think having kids at a young age is a dumb idea especially at 15. You're still in school, you never know if you and your boyfriend will last forever, what about college? What about a job? What about traveling the world? 
My friend's sister in law is 15 and she's currently pregnant and now is asking her and her fiance for help but they refuse too other families don't want to help either and I totally agree with it.
I just find it funny how I would abort in a heart beat the moment I find out I'm pregnant and I'm only 21, 
If you're going to be having kids that young then you need a back up plan. You need to do school and have a job and care for your kid. You want to act like an adult then survive like one. 
What are your thoughts on it? I grew up in a strict house hold and I'm glad I had kids and it's already hard for me to have kids as I was told which I'm totally fine with. 
Call me a Bitch for saying it but I'm just being honest.
