My daughter never wants to put diapers or clothes on. What do I do?

I am 6 months pregnant with my second child and my 16 month old daughter never wants to put on clothes nor does she ever want her diaper changed. If I change her on the floor, she picks up the clothing or diapers and runs around the room with them. If I change her on her bed, she pees all over and refuses to stay still. If I change her on my bed, she crawls away and jumps on the bed squealing and she will do all of the above for 20 or 30 minutes at a time. Sometimes, when I manage to get her to lie down she will kick me in the stomach profusely til the point where I literally have footprints on my stomach afterward from her kicking me. It's extremely frustrating because I am getting so much bigger and more exhausted that I honestly do not have the energy to chase her all over the bed or all around the room a million times a day. With this pregnancy, I have a problem with excessive sweating and the more I chase her around the more I sweat and the more aggravated and anxious I become because the sweating makes me so uncomfortable. I mean I sweat everywhere under my arms, under my boobs, in between my legs, my back, my face. I don't want to force her or yell at her because really that is the only extremely annoying thing she does, but I don't really know how to break this habit of hers. Please help!
