You could force some of the buds to produce male pollen sacs full of pollen, which can then be used to fertilize some of your buds and produce all female seeds.
Click here for more info on how to force a female plant to make pollen. From what I understand, the process of using colloidal silver to force male traits is the method used by many big seed companies to make feminized seeds.
However, your best bet is probably to keep the plants vegetating until you can get some usable clones off of her. Once you have a couple of clones, you have a lot more options. I've always had good luck cloning by taking thin, longish stems near the bottom/base of the plant. From what I understand, you want to take clones from the bottom of the plant because these cuttings will have more root stimulating hormones than cuttings taken from the top of the plant. I prepare the growing medium (I transplant my clones right into a coco coir potting mix) by watering it thoroughly with pH'ed water and creating a little hole to put my new clones. I cut the clones at a 45 degree angle and then use scissors to split the stem down the middle by about a quarter of an inch at the bottom. New roots will only form on parts of the plant that have been cut, so when you cut the slit up the middle, it makes more surface area that roots can potentially grow out of. That's also the reason for cutting the clone off the plant at a 45 degree angle. I trim all the leaves on the cutting except for the top two. I then quickly dip my cutting in plain pH'ed water, then stick an inch or two of stem right in the hole I've created and press in the coco coir firmly around the stem to prop the cutting up. My best advice with clones is to leave them alone, keep them moist but not wet, and make sure they're getting only a little bit of ambient light from something gentle like a CFL. If you give them too much light, new cuttings focus their energy on photosynthesis instead of creating new roots. I don't start really giving new clones any real light until I see signs of new growth, then I take it really easy and gently introduce light.
I know many people use cloning gel and misters, but I've had pretty good success rates using my plain water method. Some clones will show signs of new growth in only 2-3 days, and many are thriving by day 7-10.
