Last & Final question for me for today so let's make it a good one..?

Okay so I'm 17 yrs old.. I think I'm prego cuz I think I'm Spotting.. But my boyfriend wants to have it if I am cuz he's been wanting a kid. But I don't. I feel that I'm too young to have one even to I'm already outta skoo.. I already graduated and feel that a kid is gunna hold me bak.. I want to have a kid in the next 3+ years after I finish my college major.. But he's about to be 21 next week n feels he's ready for a kid.. So what do I do? Crush his dreams to Fulfill mines. Or vise versa?
