Please help me figure out what is causing my itchy skin?

about 2 weeks ago, i undertook a major cleaning of my house. Ever since then, every day I am finding anywhere from 2 to 6 new spots of itchy skin. I do have allergies to dust and everything ociated with it. I have tried everything I can think of from washing all of my linens/slip covers for the furniture to actually taking the shop vac to my furniture (including my bed). I can't stop scratching!! It's driving me crazy... I appear to be the only one getting these, my fiance doesn't have anything on him. I've been doing some research and these bites resemble bed bugs but I don't know where they would have come from. I shower on a regular basis... I don't know what else to do... I haven't changed my diet or anything. Could I have developed an allergy to my laundry detergent even though it's the same one I have always used? What else could it be?? I haven't been able to get to my dr's b/c his schedule is basically the same as my work schedule.... HELP PLEASE!
