What's wrong with me?

I'm 5 days away from my expected period and my nipples has been sore. I'm bloated and I lost all interest in sex. I've been feeling funny lately too, like I'm not myself anymore. I usually love having sex, but this is weird. I also feel sick and I got emotional during sex like I don't want to do it. My mood has been getting to the best of me lately & i get some cramps here and there. I'm also conspitated and I'm usually not conspitated. I'm not sure if a cold is related to being pregnant but I did get a runny nose for about a week and a half and it finally stopped.
