SOMETHING IS FRIGGEN BITING ME!!!

What did I do wrong here? I wake up each morning with new bug bites on my body. I have checked my dogs for fleas, I have washed the sheets and pillowcases, my husband has not retained ONE single bite. I just do not get it. What could be biting me!?!?! I am so itchy! Being itchy and 31 weeks pregnant really sucks.
