It probably will, seeing as its been going for about 2 weeks at this point. I say just recap them (your first time it always takes more force than you would think), and then wait 3 more weeks. Then come back and assess the situation if they're still under carbonated.
If it helps, I usually cap my bottles forcefully then rotate them 90 degrees and crimp them again. I don't know if that does anything, but it does make me feel better about it.
