Pms symptoms vs prego symptoms

This month has been a little off with my body lately. Normally 2 weeks before I start my period I am super dry, and don't want sex, and I have the normal pms symptoms. Well this month a week after my period I was super sexually and my fiance and I had sex almost everyday. And the. Last week Instead of being super dry and non sexually I was more sexually and I had milky white discharge that was super watery to where it's leak through my pants. ( keep in mind this never ever happens to me) now this week I'm supposed to start my period on the 1st but I don't feel the normal pms symptoms. I feel nauseated in the morning and after I eat or drink anything. I don't have my normal cramping it's more gas cramping and constipation cramping. I'm having excess saliva, my discharge is a milky white but is light, I'm more tired than I normally am when I'm about to start my periods.l, my breasts feel heavy and tender, my stomach feels different like noticibly bloated and I'm peeing more than I normally do efore my period. I'm not sure what to think right now so I'm trying to get other people's opinions on this. Can anyone give some advice?
