Baby.

My boyfriend and i are completely head over heels for each other! We recently had a pregnancy scare, we still don't know for sure if I am pregnant. I took 2 pregnancy tests one was positive but the second line was so faint you could barely see it the second one was negative. We're waiting to get a blood test but I just don't think I'm pregnant but we're both really excited/nervous about it and we've talked about how well both be kinda sad if I'm not pregnant, but we didn't plan this. But I think if I'm not pregnant I want to try.. There isn't anyone I would want to start a family with. We're young I'm 20 and he's 24 and we're both in the military so we can support a baby easy.. But, should I tell him I want to try to have a baby.. Or at least stop trying not to have one?
