Drontal is the med of choice around here for tapeworms, but any good vet would at least want to see a stool sample. And as shannon says, kitties get tapeworms from eating fleas. You will not get tapeworms from kitty, though, unless you also eat a flea. It has to pass through a certain cycle including going into your stomach.
Anyway, get Fluffy to the doc, or at least get a poo of Fluffy's to the doc; try to do it when the rice things are shedding in the stool (they don't always shed, but their absence does not mean the tapeworm has left), so you can be sure you are worming for the right thing. And don't forget flea treatment and flea control at home, such as vacuuming.
The kitten needs to be dewormed, the worms you are seeing are tapeworms. Animals get these from ingesting fleas, so she also needs monthly flea preventative. As long as you are good about washing your hands, the tapeworms do not pose a huge threat to you or your pregnancy. There are over-the-counter medications that I use on my own pets because I know which medications and how to calculate the dose, but I would try and call you vet if you have one and see if they can advise you on any over the counter medication or are willing to give you medications without seeing her. The vet has every right to have to see the kitten before prescribing any medications, but some vets will give out things for cats without seeing them.
