It does sound as if you've bottled before fermentation has finished. The question is, what to do. Be aware that if there's still some way for fermentation to go, a weaker bottle might explode. Just don't hold it up to the light in front of your face. You might try putting them upright in the fridge overnight, and then lifting an edge of the cap with a bottle opener, letting out the gas and then crimping the cap shut again. Don't worry if this results in some loss of beer. nothing infectious can get in while the inside pressure is greater than the outside. I always bottle some of the beer in PETs so that I can see what's going on.
