Fleas and pregnancy?

Before I got pregnant my boyfriend had two cats and four dogs. They mostly stay downstairs at our house till the cat had 6 kittens. His mother took the grown male cat but now we have 11 animals in total and the kittens are still a few weeks shy of being able to give away. Our house is INFESTED with fleas. Literally just laying in my bed and I can feel like all over me. My boyfriend and I gave the dogs flea medicine and have been bathing the cats but they won't go away. The animals are all now quarantined downstairs but how do I get these fleas to go away?! We don't want to flea bomb because I'm pregnant and I know that won't even work. I'm sick and tired of constantly having fleas all over me! I'm at the point I want to move out and leave him here until he figures something out because I want to give away all the dogs and cats! I'm pissed! And he nor his mother who started the flea problem know what to do and only put in a half ass effort to rid the house of them.
